Question

Determine the probability of having 0 girlsgirls and 3 boys in a 3​-child family assuming boys and girls are equally likely. what would be the fraction?

Answer 1

Answer:

1/8

Step-by-step explanation:

Let

• Event A: The first-born is a boy.

• Event B: The second-born is a boy.

• Event C: The third-born is a boy.

Considering one birth, the probability of having a boy is 0.5 or 1/2.

Each birth is independent of the previous one. The probability that independent events occur is equal to the product of the individual probabilities.

P (A and B and C) = P(A).P(B).P(C) = 1/2 . 1/2 . 1/2 = 1/8

Answer 2

3/3 is the answer to your question.
