WebFeb 14, 2024 · The binomial distribution in statistics describes the probability of obtaining k successes in n trials when the probability of success in a single experiment is p.. To calculate binomial distribution probabilities in Google Sheets, we can use the BINOMDIST function, which uses the following basic syntax:. BINOMDIST(k, n, p, cumulative) where: … WebAnd we have (so far): = p k × 0.3 1. The 0.3 is the probability of the opposite choice, so it is: 1−p. The 1 is the number of opposite choices, so it is: n−k. Which gives us: = pk(1-p)(n …
