Ryder tossed two coins 50 times.He recorded two heads 11 times.
A)what is the experimental probability of obtaining two heads as a percent?

b)the theoretical probability of obtaining two heads is 25%.How could Ryder repeat the experiment to obtain an experimental probability closer to 25%?

1. P = positive results / total attempts. In this case, 11/50 = .22 = 22%

2. Increase the sample size. The more data he accrues, the closer the experimental probability will be to the theoretical probability.
