Approximately 125 families out of 1,000 to have exactly 2 boys and 1 girl.
How to solve
Probability of one child being a boy: 50%
Probability of another child being a boy: 50% (independent event)
Probability of the third child being a girl: 50% (independent event)
Probability of having 2 boys and 1 girl: Multiplying individual probabilities: 0.5 * 0.5 * 0.5 = 0.125 (12.5%)
Therefore, based on this sample set and probability calculation, we would expect approximately 125 families out of 1,000 to have exactly 2 boys and 1 girl.
The Complete Question
Out of 1,000 families, each with 3 children, and assuming boys and girls are equally likely for each child, how many families would you expect to have exactly 2 boys and 1 girl?
Set Data:
Imagine simulating 1,000 families with 3 children each, flipping a coin (heads = boy, tails = girl) for each child's gender. This would be a simplified representation of random chance determining the gender of each child.
