21 and the Monty Hall Paradox Monday, September 08, 2008 Bringing Down the House by Ben Mezrich is, so far as I know, the only book which has ever succeeded in writing about the game of blackjack in an interesting way. No offense to blackjack authors/players, but blackjack suffers from the same problem that afflicts poker: it can be a lot of fun to play, but often not much fun to read about playing. As an old blackjack-pro-turned-poker-player once wrote: Blackjack is a game of pure numbers and rote, algorithmic strategy, and the life of a professional blackjack player (as professional blackjack players will agree) can be an exceedingly dull grind. Why should anybody contend with huge variance relative to a measly 1-2% gain, hostile casino staff, and hours of never-ending boredom? Masochism? For this reason, I believe that inside every casino blackjack player is a poker player, waiting to get out . In poker , the edge is a fat 10%, 15%, 20% by some estimates. In poker, there is no hostile casino staff, only people who are glad you showed up to play. In poker, you can make more money in a year than many people will make in a decade, and you can do this even if you're not a world-class player. Compared to blackjack, the game of poker is like a breath of fresh air. For this reason, I think

71. Conditional Probability Conditional Probability, The Monty Hall Problem. Sometimes we already know the ocurrence of an event A, then the probability of a relevent event B given A is different from P(B http://www.math.cornell.edu/~mec/2008-2009/TianyiZheng/Conditional.html

Conditional Probability, The Monty Hall Problem Sometimes we already know the ocurrence of an event A, then the probability of a relevent event B given A is different from P(B) without any information on A. Since the sample space is reducedd from the total space to A and the probability that B will occur given that A has occured is Example: Suppose we throw two fair dices. Consider the following three events: A : Dice 1 lands on 3 B : Dice 2 lands on 1 C : The sum is 8 First notice that C C )=5/36. Obviously, P( A )=1/6 and P( B )=1/6. Sometimes this is called the priority probability of each event. Next, we have 'Both A and C B and C occur'=empty and 'Both A and B A intersects C )=1/36 , P( B intersects C )=0 and P( A intersects B Then you can compute all the conditional probabilities using the priority probability and joint probability given above. Notice that we have When the above equation holds for two events A and B, we say they are (statistically) independent. Intuitively, this means that the two events don't interfere with each other. Equivalently, independence means that As the last example may have suggested, the mapping from event B to conditional probability of B given A (A a fixed event) is a probability. You may look up the axioms of probability and check the conditions one by one.

Home Printables All Games Math Games ... Math Games Monty Hall Game Find out the truth of Monty Hall's old Three Door Game by playing this online simulation! var addthis_pub="dtwitchell"; Monty Hall's Three Door Puzzle If you are not familiar with the Monty Hall Three Door puzzle, the premise is this: There is a prize behind one of three doors. The game show host (Monty Hall) invites you to pick a door. Once you've picked a door, instead of opening it, Monty points at one of the other doors, and says "That one is empty." Now he gives you a choice. Do you keep your guess? Or do you switch to the other possible door? There are three different answers people give to this question: It doesn't matter which I choose I'll keep my guess - my odds are better that way I'll change my guess - my odds are better that way Which way would you play? When you play this game, you can find out which method works the best. Try always changing your guess. Try always keeping it the same. Try being random. Does it work the way you expected? Or were you surprised?

ENCYCLOPEDIA U com Lists of articles by category ... Encyclopedia Home Page Web Encyclopedia4u.com Monty Hall problem The Monty Hall problem is a riddle in elementary probability that arose from the American game show "Let's make a deal" with host Monty Hall . In spite of being an elementary problem, it is notorious for being the subject of controversy about both the statement of the problem and the correct answer. The problem is as follows: At the end of the show, a player is shown three doors. Behind one of them, there's a prize for him to keep, while the other two contain goats (signifying no prize to be won). Although the show host knows what is behind each door, of course the player does not. After the player makes a first choice, Monty opens one of the two other doors, revealing a goat. He then offers the player the option to either stick with the initial choice or switch to the other closed door. Should the player switch? The classical answer to this problem is yes , because the chances of winning the prize are twice as high when the player switches to another door than they are when the player sticks with their original choice. This is because upon the original choice, the player has only a 1/3 chance of choosing the door with the prize; this probability does not change when Monty opens a door with a goat. Hence the chances of winning the prize are 1/3 if the player sticks to their original choice, and thus 2/3 if the player switches. Instead of one door being opened and thus eliminated from the game, it may equivalently be regarded as combining two doors into one, as a door containing a goat is essentially the same as a door with nothing behind it. In essence, this means the player has the choice of either sticking with their original choice of door, or choosing the sum of the contents of the two other doors. Clearly, the chances of the prize being in the other two doors is twice as high.

You're planning to write to me about the Monty Hall Problem, aren't you. That's why you've clicked onto this page. I can see it in your mad, swivelling eyes. Well, don't. Please. I get many letters explaining, at great length, why I've got it wrong . I've finally given up answering them. Life is just too short. The Monty Hall Problem is famous precisely because the correct answer is so infuriatingly counter-intuitive. The irony is that if you play the game (all you need is three squares on a piece of paper, a pencilled cross and a dice) it becomes rapidly obvious that the 'change' tactic increases your probability of finding a car. But there are many very intelligent people who believe that thinking about something is superior to doing it...

Return to my Puzzle pages Go to my home page The Monty Hall Trap This puzzle (also called the Monty Hall problem) has become fairly famous. If you've never seen it, you won't believe the answer that I will give below. Suppose that Monty Hall (on TV's Let's Make a Deal ) asks you to choose between three doors: #1, #2, and #3. Behind a random door is a new Rolls Royce. Behind each of the other two doors is a goat. Let's assume that you would prefer a Rolls Royce to a goat. You choose a door. Now, Monty, who knows which door hides the Rolls Royce, shows you a goat behind one of the two doors that you did not choose. He then gives you the opportunity to change your choice. Assume that Monty always does this, regardless of your guess. Should you change your choice? There is a fairly simple solution to this. But, people don't believe it. There has been much heated debate over it. I'll show my reasoning below. And then, see if you agree. Originally, your chances of choosing the correct door are one in three. Monty, who knows where the Rolls Royce is, shows you a goat behind another door. It will turn out that he did not change your odds. You still have one chance in three of being right. So you should switch to the remaining door, which now has odds of 2/3. You probably don't believe that Monty did not change the odds of your first guess being right. He showed you a door, seemingly at random. So, aren't the odds now 50-50 for the two unseen doors? Of course, Monty's choice of doors was not at random. But, what difference does that make?

Home The question you have to answer is whether or not you increase your chances of winning the Ferrari by switching your original choice to the remaining unopened door. So to repeat: There are three doors, one has a Ferrari behind it, the other two, goats. You choose a door. One of these two remaining doors has a goat behind it, the other a Ferrari. Will you increase your chance of winning the Ferrari if you switch from your original choice, and ask Monty to open the other door? To make your choice, select one of the options below, then click the Submit button! Switch - I'm going to increase my chances of winning if I switch. Don't Switch - There are two doors, one has a goat, the other a car. It makes no difference if I switch. It's a fifty-fifty chance.
