Question

What is the experimental probability that exactly 3 children in a family of 4 children will be boys? Assume that P(boy) = P(girl). Solve by simulating the problem. Please explain.

Answer 1

Everyone who does this problem will get a slightly different answer. I would get four coins to toss. Suppose you let H represent a male child and T represent a female child.

Before tossing the coins, make a chart with:

Zero Boys
One Boy
Two Boys
Three Boys
Four Boys

When you toss the four coins, count the number of Heads and place a mark in the chart next to that number of boys.

Repeat for 50 tosses of the group of 4 coins. That represents 50 families of 4 children.

Look at the total of the families that had three boys.
Divide it by 16 and that is the experimental probability of a four-child family having exactly three boys of the four children.
