The only option without a boy is the fourth.

3/4 possibilities results in having at least 1 boy

Answer: .75

The probability that when a couple has two ​children, at least one of them is a boy is 0.75.

Based on the information given, the sample space will be (BB, BG, GB, GG)

where,

B = Boy

G = Girl
