FOUR PRACTICE PROBLEMS--PERMUTATIONS AND …

As you pick up your cards, what is the probability of picking up four aces, followed by a non-ace? By the multiplicative rule, this is: 4/52 x 3/51 x 2/50 x 1/49 x 48/48 = 0.0000036937852. But you do not have to get the four aces first and the non-ace last. You could get the non-ace fourth: 4/52 x 3/51 x 2/50 x 48/49 x 1/48 = 0.0000036937852. ................
