Identify X from the problem. This means that there are a countable number of outcomes that can occur in a binomial distribution with separation between these outcomes. An experiment is nothing but a set of one or more repeated trials resulting in a particular outcome out of many outcomes.
The criteria of the binomial distribution need to satisfy these three conditions.
This tutorial explains how to use the following functions on a TI-84 calculator to find binomial probabilities. The mean of the binomial distribution is interpreted as the mean number of successes for the distribution. It is important to know when this type of distribution should be used. Calculate the combination between the number of trials and the number of successes.
