Find the variance of the number obtained on a throw of an unbiased ***.

Question 1

Question 2

The sample space of the experiment is * = {1, 2, 3, 4, 5, 6}.

Let X denote the number obtained on the throw. Then X is a random variable which can take values 1, 2, 3, 4, 5, or 6.

Also P(1) = P(2) = P(3) = P(4) = P(5) = P(6) = 1/6

Therefore, the Probability distribution of X is

| X | 1 | 2 | 3 | 4 | 5 | 6 |
| P(X) | 1/6 | 1/6 | 1/6 | 1/6 | 1/6 | 1/6 |
