Part 6 20 points] Create a class called BinomialRandomVariable in a class file called BinomialRandom Vari- able.java that extends the class BernoulliRandom Variable. This class should have the fol- lowing fields/methods: One field int n (where n stands for the number of trials One method called get Mean() accepts no arguments returns a double calculates and returns the mean for a Binomial random variable with parameters p and n using the following equation: E[X] = np where X is a Binomial random variable One method called get Variance() - accepts no arguments returns a double calculates and returns the variance for a Binomial random variable with parameter p using the following equation: V[X] = np(1 p) where X is a Binomial random variable One method called PMFO - accepts an integer named - returns a double equal to the value of P(X = 1) - calculates P(X = ?) using the following equations: P(X = 1) = (?)p(1 py(az) for 0
