Refer to Exercise 4.31. Suppose the elementary outcomes are assigned these probabilities.

(a) Find P(A), P(B),and P(AB).

(b) Employing the laws of probability and the results of part (a), calculate P(A¯) and P( A U B).

(c) Verify your answers to part (b) by adding the prob abilities of the elementary outcomes in each of A¯ and A U B.

Data from Exercise 4.31:

Next week, a student worker will be assigned one morning of kitchen duty. The sample space has seven elementary outcomes e1 , e2, .. , e7 where e1 represents Sunday, e2 Monday, and so on. Two events are given as A = {e4 , e5, e6 , e7) and B = {e1, e6 , e7).
