Binomial Distribution Expected Value Formula

Learn how to find the expected value of a binomial random variable with this quick tutorial. The question addressed is: Let X follow a binomial distribution with parameters n and p. What is the formula for the expected value E(X) of X? The correct formula is E(X) = np, which means if you have n trials and the probability of success in each trial is p, on average, you can expect np successes. This is part of the Probability distributions chapter in 12th grade Mathematics & Statistics. Perfect for students looking for a concise explanation of binomial distribution concepts.
