Quizplus · Accepted Answer

The total number of possible combinations of children in a family of 5 is 2^5=32 (2 choices for each child). The number of ways to have 3 girls and 2 boys can be calculated using the binomial coefficient formula: C(5,3) = 10. Therefore, the probability of having 3 girls and 2 boys is 10/32 = 0.3125.
