Binomial Probability with TI-84

This video tutorial demonstrates how to calculate binomial probabilities using a TI-84 calculator. It provides two examples: one where the random variable X equals 1 with 8 trials and a success probability of 0.2, and another where X equals 4 with 9 trials and a success probability of 0.3. The video explains how to use the TI-84's distribution menu and the binomial PDF function to find these probabilities. It also shows how to calculate the probabilities manually using the binomial formula, including combinations and powers of probabilities.
