Tree and Venn Diagrams · Exercise 7
The percent of licensed U.S. drivers (from a recent year) who are female is 48.60. Of the females, 5.03 percent are age 19 and under; 81.36 percent are age 20–64; 13.61 percent are age 65 or over. Of the licensed U.S. male drivers, 5.04 percent are age 19 and under; 81.43 percent are age 20–64; 13.53 percent are age 65 or over.
Complete the following:
(a) Construct a table or a tree diagram of the situation.
(b) Find P(driver is female).
(c) Find P(driver is age 65 or over|driver is female).
(d) Find P(driver is age 65 or over AND female).
(e) In words, explain the difference between the probabilities in Part c and Part d.
(f) Find P(driver is age 65 or over).
