When a person is selected at random from a very large population, the probability that the selected person
is right-handed is 0.82. If three people are selected at random, what is the probability that
(a) They are all right-handed?
(b) None of them is right-handed?
(a) P = = 0.5514. ANSWER
(b) P = = = 0.005832. ANSWER
Solved.
