Amrita flips a biased coin repeatedly until she observes that both a head and a tail appear.The probability that a head will appear on a single flip is p, for 0 < p < 1. Find the probability mass function of N, the number of flips required to observe both a head and a tail. Hint: If N is the flip number that ends the experiment then that means that the N − 1 flips previous to flip N must all be the same as each other but different from the Nth flip. Also think about what the smallest value in the support of N must be. Finally remember that there are two cases: a sequence of tails followed by a head, or a sequence of head’s followed by a tail.
The General Social Survey asked a sample of adults how many siblings (brothers and sisters) they had (X) and also how many children they had (Y). We show results for those who had no more than 4 children and no more than 4 siblings. Assume that the joint probability mass function is given in the following contingency table: y x 0 1 2 3 4 0 0.03 0.01 0.02 0.01 0.01 1 0.09 0.05 0.08 0.03 0.01 2 0.09 0.05 0.07 0.04 0.02 3 0.06 0.04 0.07 0.04 0.02 4 0.04 0.03 0.04 0.03 0.02 Find ρ(X, Y).

A harried passenger will be several minutes late for a scheduled 10 A.M. flight to NYC. Nevertheless, he might still make the flight, since boarding is always allowed until 10:10 A.M., and boarding is sometimes permitted up to 10:30 AM. Assuming the end time of the boarding interval is uniformly distributed over the above limits, find the probability that the passenger will make his flight, assuming he arrives at the boarding gate at 10:25.
