The probability of a persons being lefthanded is 12 In the 1

The probability of a person\'s being left-handed is .12. In the 1992 U.S. presidential election

all three major candidates were left-handed. What\'s the probability of selecting three

unrelated people who are all left-handed?

Solution

Unrelated people have independent left-handedness.

Thus,

P(all three left handed) = 0.12*0.12*0.12 = 0.001728 [answer]
