Question 1177794: Question 6.59 from the book Statistics for Management and Economics, page 176
Refer to exercise 6.29. Suppose that, instead of providing the joint probabilities, the analysis yielded the following information:
1. The proportion of males in the electorate is 42%.
2. Gender and voting record are independent.
3. The proportion of eligible voters who voted in the last elections equals 43%.
a. P(Voted in last election and male)
b. P(Voted in the last election and female)

.

(a)  P(Voted in last election and male) = 0.43*0.42.  Use your calculator.



(b)  P(Voted in the last election and female) = 0.43*(1-0.42).   Use your calculator.

Solved.

The formulas used are self-explanatory.
