example: What is the probability that Dolores makes no more than 5 free throws? That is, what is P(X ≤ 5)?

solution:

There is about a 25% chance that she will make 5 or fewer free throws. The solution to this problem using the calculator is given by binomcdf (10,0.65,5).

example: What is the probability that Dolores makes at least 6 free throws?

solution: P(X ≥6) = P(X = 6) + P(X = 7) + … + P(X = 10) = 1-binomcdf(10,0.65,5)=0.751.

(Note that P(X > 6) = 1 – binomcdf(10,0.65,6)).

The mean and standard deviation of a binomial random variable X are given by μx = np; . A binomial distribution for a given n and p (meaning you have all possible values of x along with their corresponding probabilities) is an example of a probability distribution as defined in Chapter 7. The mean and standard deviation of a binomial random variable X could be found by using the formulas from Chapter 9:
