Question
A basketball player has a 0.689 probability of making a free throw. If the player shoots 18 free throws, what is the probability that she makes no more than 11 of them?
Answer
This probability can be found using the binomial distribution with success probability p=0.689 and 18 trials. To find the probability that no more than 11 of the free throws are made, use a calculator or computer: P(X≤11)=binomcdf(18,0.689,11)=0.314.
