10 · 9 · 8 · 7! = = 120 7! · 3! 7! · 3 · 2 · 1 This process is easily generalized. If we have nr distinct samples, each of these can be permuted in r! ways, yielding all the permutations of n objects taken r at a time, so r! · n r n r = = n! (n − r)! or n! r! · (n − r)! 52 5 then represents the total number of possible poker hands. This is 2, 598, 960. This number is small enough so that one could, given enough time, enumerate each of these. This calculation by hand would appear this way: 52 5 = 52!

It matters. The contestant who switches has probability 2/3 of winning the prize. If the contestant does not switch, the probability is 1/3 that the prize is won. In thinking about the problem, note that when the empty door is revealed, the game does not suddenly become choosing one of the two doors that contains the prize. The problem here is that sometimes Monty Hall has one choice of door to show empty and sometimes he has two choices of doors that are empty. This must be accounted for in analyzing the problem.

When we captured some tanks, say, we could then estimate the total number of tanks they had from the serial numbers on the captured tanks. Here we will consider maximum likelihood estimation: we will estimate n as the value that makes the sample median we observed most likely. 0537549 Now let us compute a table of values of n and these probabilities, letting m = 8 for various values of n. 5. 3). We see that the maximum probability occurs when n = 13, so we have found the maximum likelihood estimator for n.
