We have a two-stage event A, B with corresponding probabilities P(A) = 1/3 and both stages have
two possible event outcomes C, D with P(CIA), P(DA), P(CIB) and P(DIB). Here some second
stage event probabilities given as P(C|A) = 3/5 and P(D|B) = 7/10.

(a) Find the probability that event B occurred in the first stage and event D occurred in the
second stage. (b) Find the probability that event D occurred in the second stage. (c) Suppose
we are given the information that event D occurred. Find the conditional probability that event
B occurred in the first stage by use of the Bayes' theorem. (Write the Bayes' theorem formula
first for this question.)
