i) A random variable X has a binomial distribution with mean 6 and variance 3.6. Find P(X = 4)
ii) Let X equal the larger outcome when a pair of four-sided dice is rolled. The pmf of X is f(x) = 27-1 16 =1,2,3,4
Find the mean, variance and standard deviation of X.
iii) Let pand o denote the mean and variance of the random variable X. Determine E(X-Mo and E{[X-X)/]}
