Let X1, X₂,... be independent variables each taking the values 0 or 1 with probabilities 1 - p andp, where 0 < p < 1. Let N be a random variable taking values in the positive integers, independentof the X₁, and write S = X₁ + X₂ + + XN. Write down the conditional generating function of Ngiven that S = N, in terms of the probability generating function G of N. Show that N has a Poissondistribution if and only if E(x)P = E(xN | S = N) for all p and x.

A factory received a shipment of 15 capacitors, and the vendor who sold the items knows there are 8 capacitors in the shipment that are defective and 7 are not defective. Before the receiving foreman accepts the delivery, he samples the shipment, and if too many of the capacitors in the sample are defective, he will refuse the shipment. Give answer as a decimal to four decimal places.(a) If a sample of 6 capacitors is selected, find the probability that all in the sample are defective. (b) If a sample of 6 capacitors is selected, find the probability that 4 in the sample are defective. (c) If a sample of 3 capacitors is selected, find the probability that 1 in the sample are defective.
Assume that the airline still sells 340 tickets for the 280-seat flight, but that all tickets are sold in groups of 4 and that each group of four only shows up with probability 0.854, since the entire group will only travel if all four in the group can travel. Compute the exact probability that there will be enough seats for everyone who shows up, noting that each party only shows up in full or not at all. Express your probability to three decimal places.
A random number generator produces sequences of independent digits, each of which is as likely to be any digit form of 0 to 9 as any other. If X denotes any single digit, find the mean or expected value of the probability distribution.
