Find the experimental probability that 4 of 4
children in a family are boys.
The problem has been simulated by tossing 4
coins (one to represent each child). Let "heads"
represent a boy and "tails" represent a girl. A
sample of 20 coin tosses is shown.

Answer:

5%

Explanation:

I didn't see any more than I HHHH

There are 20 total tosses.

1 was successful

P(4 heads)= 1/20

Experimental Probability = 1/20 * 100 = 0.05 * 100 = 5%

If you see more than one HHHH put the number that you count over 20 and multiply by 100.
