Of all airline flight requests received by a certain discount ticket broker, 80% are for domestic travel (D) and 20% are for international flights (I). Let x be the number of requests among the next three requests received that are for domestic flights. Assuming independence of successive requests, determine the probability distribution of x. (Hint: One possible outcome is DID, with the probability (0.80)(0.20)(0.80) = 0.128.) Value of x Probability 0   1   2   3

D = domestic flight.

I = International flight,

P(D) = 0.80, P(I) = 0.20

X : number of requests among the next three requests received that are for domestic flights
