A computer consulting firm presently has bids out on three projects. Let A, = {awarded project i}, for i = 1, 2, 3, and suppose that P(A,) = P(A, N A.) = .11, P(A, N A;) = .05, P(A, N A,) = .07, P(A, N A, N A,) = .01. Express in words each of the fol- lowing events, and compute the probability of each event: a. A, U A2 b. A{N A; [Hint: (A¡ U A,)' = A¡ N A'] c. A, U A, U A3 e. A N A', N A3 3 .22, Р(А) 3 .25, Р(А,) %3 .28, d. A¡ N A', NA'3 f. (A' N A';) U A3
