We want the probability of making a basket on at most 7 free throws. Cumulative Binomial Probability: given a random variable X, the cdf of X calculates the sum of the probabilities for 0, 1, 2, …, up to the value of X. That is, it calculates the probability of obtaining at most X successes in n trials.

CDF – cumulative (probability) distribution function; assigns the sum of probabilities less than or equal to X. Key Concepts: Mean and Standard Deviation: TI-83 Support: For P(X = k) using the calculator: 2nd VARS geometpdf(p,k) For P(k ≤ X) using the calculator: 2nd VARS geometcdf(p,k) For P(X > k) use 1 – P(k ≤ X) or (1- p)k
