If X has a binomial distribution with n observations and probability p of success on each observation, the possible values of X are 0, 1,2,3,…,n. If k is any one of these values, then. The Probability Distribution Function (pdf) assigns a probability to each value of X. On your calculator, you can use binompdf (n, p, X). Example:

Evaluate a binomial probability by using the mathematical formula for P(X = k). Explain the difference between binompdf(n, p, X) and binomcdf(n, p, X). Use your calculator to help evaluate a binomial probability. If X is B(n, p), find µx and (x (that is, calculate the mean and variance of a binomial distribution).

x. be the number of easy puzzles Tina solved. Then, 50 minus x. is the number of hard puzzles she solved. And since she earned a total of 1,950 points, it must be true that 30 x. plus 60, open parenthesis, 50 minus x, close parenthesis, equals 1,950. Solving this equation for . x. gives . x equals 35, and so 50 minus x. equals 15.

When X is B (10, 0.1). The calculator command for this is binompdf (n,p,X). PDF stands for probability distribution function. Type in both binompdf (10, 0.1, 0) and binompdf (10, 0.1, 1) and see what values you get. Example 8: Corrine is a basketball player who makes 75% of her free throws. In a key game, Corrine shoots 12 free throws and makes ...
