Binomial Probability Using Desmos

This video tutorial demonstrates how to determine binomial probabilities using Desmos.com. It covers two examples, each with a binomial distribution, and shows how to graph the distribution and calculate probabilities using both Desmos and a mathematical formula. The first example involves a distribution with 8 trials and a success probability of 0.2, while the second example has 9 trials and a success probability of 0.3. The video provides step-by-step instructions for using Desmos to visualize the distribution and calculate probabilities, as well as how to apply the binomial probability formula.
