The probability that Rahul succeeds at any given free-throw is 70%. He was curious how many free-throws he can expect to succeed in a sample of 15 free-throws.

He simulated 30 samples of 15 free-throws where each free-throw had a 0.7 probability of being

successful

Rahul counted how many free-throws were successful in each simulated sample. Here are his results:

10 11 12 13 14 15

# of free-throw successes

Use his results to estimate the probability that he succeeds at 11 or fewer free-throws in a sample of 15

free-throws.

Give your answer as either a fraction or a decimal.

P(11 or fewer successes)
