Question
A computer-consulting firm presently has bids out on three projects. Let
A, = awarded projecti, for i =1,2,3.
Suppose that P(A) =.22, P(A,)= .25, P(A,)=.28, P(AnA,)=.11,
P(4,N 4.) = .05, P(A, N 4,) = .07, P(4, 0 4, 04.) =.01.
A. Express in words each of the following events, and compute the
probability of each event.
a. A U A,
c. AN AN 4,, and
B. Are the three events pairwise independent? Find the conditional probability,
P(A, I A.) and interpret the probability.
