Calculation of binomial distribution can be done as follows: P (x=6) = 10 C 6 * (0.5) 6 (1-0.5) 10-6 = (10!/6! (10-6)!)*0.015625* (0.5) 4 = … WebDefinition 3.3. 1. A random variable X has a Bernoulli distribution with parameter p, where 0 ≤ p ≤ 1, if it has only two possible values, typically denoted 0 and 1. The probability mass function (pmf) of X is given by. p ( 0) = P ( X = 0) = 1 − p, p ( 1) = P ( X = 1) = p. The cumulative distribution function (cdf) of X is given by. johnstown pa central park
