Quizplus · Accepted Answer

The probability of having a boy or a girl is 1/2 each time (assuming they have no genetic predisposition for one gender over the other). Therefore, the probability of having 3 boys in a row is calculated by multiplying the probabilities of having a boy each time:

1/2 * 1/2 * 1/2 = 1/8

Therefore, the answer is A) 1/8.
