Outside the airport terminal, at the shuttle stop, you sometimes wait a long time for the right shuttle that will take you to your hotel. You are quite annoyed to see many other shuttle vans passing. Suppose the total number of shuttle vans N you see passing, until at last you board the right one, is a geometric random variable with parameter p = 0.02. What is the probability P[N > 100]...?

Prove (a) cosh2(x) β sinh2(x) = 1 and (b) 1 β tanh 2(x) = sech 2(x). solution (a) cosh2(x) β sinh2(x) = ex + eβx 2 2 β 2 = e2x + 2 + eβ2x 4 β = 4 = . (b) we start with the identity proved in part (a): cosh2(x) β sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 β sinh2(x) cosh2(x) = 1 or 1 β tanh 2(x) = .
