WebOct 19, 2024 · 2. Binomial Distribution. A binomial experiment is a statistical experiment, where a binomial random variable is the number of successes (x) in repeated trials of a binomial experiment (n). The probability distribution of a binomial random variable is called a binomial distribution. Conditions of the Binomial Distribution WebP ( 3 ≤ X < 5 ), where X is the number of trials of a negative binomial random variable with p =0.8 and r =3. As mentioned in the question, Excel takes input as the number of failures before a certain number of successes occur, and not the number of trials.
