Question:
Q. 1. We have a number of independent events A,,i = 1,2,..., n, with P(A) = p for all i. Let X= IA, and Sn = Xi.
a. (1p) Express E[X] in terms of p.
b. (1p) Express E[S] in terms of p.
c. (1p) Compute the MGF of Xi.
d. (1p) Compute the MGF of Sn
e. (1p) Use the MGF of S,, to compute E[S]. (If you don't know the MGF of S, then just assume it is A/(-s) for some \ > s.)
