Discrete Uniform Random Variable
Suppose X is a random variable with probability distribution given by
P(x) = 1/5
X=1, 2, 3, 4, 5
a. Find the mean, variance, and standard deviation of X.
b. Suppose p(x) = 1/6, x = 1, 2, 3, 4, 5, 6. Find the mean, variance, and standard deviation of X.
c. Suppose p(x) = 1/n, x = 1, 2, 3, c, n. Find the mean, variance, and standard deviation of X in terms of n.
