The probability that Maria succeeds at any given free-throw is 75%. She was curious how many free-throws she
can expect to succeed in a sample of 10 free-throws.
She simulated 25 samples of 10 free-throws where each free-throw had a 0.75 probability of being a success.
Maria counted how many free-throws were successes in each simulated sample. Here are her results:
5 6 7 8 9 10
# of free-throw succes
Use her results to estimate the probability that she succeeds at fewer than 7 free-throws in a sample of 10
free-throws.
Give your answer as either a fraction or a decimal.
