A pair of dice is rolled twice. Find the probability distribution of no. of doublets.

Explanation

To find the probability distribution of the number of doublets when a pair of dice is rolled twice, we can follow these steps:

### Step 1: Define the Random Variable
Let \( X \) be the random variable representing the number of doublets obtained when rolling a pair of dice twice. The possible values of \( X \) are 0, 1, or 2.

### Step 2: Total Outcomes
When rolling a pair of dice, each die has 6 faces. Therefore, the total number of outcomes when rolling two dice is:
\[
