= .50 is four, that's in the midst of the distribution. The suggest of the distribution n = eight and p = .20 is 1.6, which ends up in the top possibilities being close to x = 2 and x = 1. This graph peaks early and stretches towards the better values of x. The suggest of the distribution n = eight and p = .80 is 6.4, which leads to the top possibilities being close to x = 6 and x = 7. therefore the height of the distribution is closer to eight than to zero and the distribution stretches again towards x = zero. In any binomial.
