... can be written as the sum of the probabilities of 10 events Ai , where Ai is the event that the i-th man gets his own hat back. It is not hard to see that #Ai = 9! for each i, so P (Ai ) = 101 and E (f ) = 10 101 = 1: on the average, one man gets his own hat back! This remains true for any (positi ...

Chapter 4: Probability and Counting Rules
... There are times when we want to find the probability of two or more events. For example, when selecting a card from a deck we may want to find the probability of selecting a card that is a four or red. In this case there are 3 possibilities to consider: The card is a four The card is red The c ...
