Problem 77E
Let the random variable X have a discrete uniform distribution on the integers 1 ≤ x ≤ 3. Determine the mean and variance of X.
ANSWER:
Solution 77E
Step1 of 3:
Let us consider a random variable X, it follows discrete Uniform distribution with [1, 3].
We need to determine the mean and variance of X.
Step2 of 3:
Suppose that a random variable X follows discrete Uniform distribution with parameters [a, b]. Then, the probability mass function of Unifor
