... so that every assignment of the hats to the persons is equally likely). What is the probability that (a) every person gets his or her hat back? Answer: n1! . Solution: consider the sample space of all possible hat assignments. It has n! elements (n hat selections for the first person, after that n − ...

... Solution: We think of paths from (0, 0) to (n+1, n+1) as “words” of letters U and R, where U denotes a step up and R denotes a step to the right. We construct a bijection between the paths counted by Cn+1 and the paths counted on the right side. Suppose we have a path from (0, 0) to (n + 1, n + 1). ...
