question_answer Answers(3) The probability that each child will be a boy is 1/2. The probability that each child will be a girl is 1/2. The probability of at least 1 boy = 1 – the probability of no boys. boys which = 3/8 + 3/8 + 1/8 = 7/8.

What is the probability that the family has more than one child?

What is the probability of all three children being girls?

How many possible combinations of 2 boys and a girl?

As we have seen from the other answers, there are 3 permutations out of 8 which contain 2 boys and a girl. But what if we looked at the combinations instead? The combinations of 2 genders among 3 children are: 2 girls, 1 boy can be rearranged, and the boy can have 3 positions (youngest, middle or oldest).

What is the probability that the dominant phenotype will be dominant?

Let’s ask a somewhat more complex question. If this couple has a total of four children,…
