We can find both m and s for a binomial probability distribution or any other type of discrete probability distribution by using the 1-Var Stats command. TI-8384 users can use the program in MATH200A part 3 or the calculator procedure here in Stats without Tears to compute binomial probability. This shows how to calculate binomial probabilities on the TI-NSpire.
Number of trials n probability of a success p number of successes kIn other words binompdfn p kFind the binomial probability function.
Your calculator will output the binomial probability associated with each possible xvalue between 0 and n inclusive. We added these proba-bilities together to get cumulative binomial probabilities. This tutorial explains how to use the following functions on a TI-84 calculator to find binomial probabilities. The sum of the probabilities in this table will always be 1.
