(a) What is the probability that an employee of the company chosen at random had investments in exactly two kinds of investment funds? (Enter your answer to three decimal places.)
Exactly 2 kinds: 26+12+12 = 50
50/200 = 0.25
(b) What is the probability that an employee of the company chosen at random had investments in exactly one kind of investment fund? (Enter your answer to two decimal places.)
Exactly one kind: 60+40+20 = 120
120/200 = 0.60
(c) What is the probability that an employee of the company chosen at random had no investment in any of the three types of funds? (Enter your answer to three decimal places.)
60+40+20+26+12+12+21=191
200-191 = 9
9/200 = 0.045
