Solving "at least" and "at most" binomial probabilities step by step, plus the help of the TI-84 and Desmos (www.desmos.com). I will show you how to solve a binomial probability with cases using the formula, the graphing calculator, and the free site Desmos. I will you show you one example with an at most probability, and a second example with an at least.
