Question

What is the probability of a family with three children having two boys?

1) 1/2
2) 1/3
3) 2/3
4) 3/4

Answer 1

The probability of a family with three children having two boys is 2/3.

The correct answer is option 3) 2/3.

Step-by-step explanation:

The probability of a family with three children having two boys can be determined using the concept of combinations.

In this case, we want to find the probability of having 2 boys and 1 girl out of 3 children.

The number of ways to have 2 boys and 1 girl is 3 (BBG, BGB, GBB), out of a total of 8 possible outcomes (2^3).

Therefore, the probability is 3/8.
