1 Binomial Calculator-B 2/10/2010 Binomial Problems using the TI-83 A binomial experiment conditions: 1. The experiment is repeated a fixed number of times. Each time we repeat the process it is called a trail. 2. There are two possible outcomes for each trial. The outcomes are classified as a success or as a failure. 3. The probability of a success is the same for each trial. 4. The random variable x, is the total number of successes in the fixed trials. Notation n = the number of trials p = P(S) = probability of a success for a single trial q = P(F) = probability of a failure for a single trial q = 1 p x = the total number of successes in n trials Calculation of binomial experiments There is a table in the appendix that sometimes works for specific values but does not give us a lot of options. We will be using our calculator to find probabilities. Let s try a problem Suppose someone had a multiple choice exam with 10 questions. Each question had four possible answers to choose from but only one was
