gives the binomial probability of exactly x successes for a binomial random variable X that has B(n, p ).

Now,

On the TI-83/84,

and this is found in the MATH PRB menu. n! (“n factorial”) means n (n – 1)(n – 2) … (2)(1), and the factorial symbol can also be found in the MATH PRB menu.

example: Find B (15, .3, 5). That is, find P (X = 5) for a 15 trials of a binomial random variable X that succeeds with probability 0.3.

solution:

(On the TI-83/84, can be found

in the MATH PRB menu. To get , enter 15n Cr 5. )
