Find probability of binomial distribution
WebIn probability theory and statistics, the negative binomial distribution is a discrete probability distribution that models the number of failures in a sequence of independent and identically distributed Bernoulli trials before a specified (non-random) number of successes (denoted ) occurs. For example, we can define rolling a 6 on a dice as a … WebStep 5: Calculate the probability for the binomial distribution, using the formula with x = 9, n = 12, p = 0.72, and q = 0.28. This goes as follows: Thus, P(X) = 0.25112.

If a discrete random variable X has the following probability density function (p.d.f.), it is said to have a binomial distribution: P (X = x) = n C x q (n-x) p x, where q = 1 - p. p can be considered as the probability of a success, and q the probability of a failure. Note: n C r (“n choose r”) is more commonly ...
