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 = 0.82%5E3 = 0.5514.    ANSWER


(b)    P = %281-0.82%29%5E3 = 0.18%5E3 = 0.005832.     ANSWER

Solved.
