A random varibale X has the following probability distribution.
`{:(X:,1,2,3,4,5),(P(X):,0,0.1,0.2,0.3,0.4):}`
Find the mean.

Explanation

To find the mean of the random variable \( X \) with the given probability distribution, we will follow these steps:

### Step 1: Write down the values of \( X \) and their corresponding probabilities \( P(X) \).

The values of \( X \) and their probabilities are:
- \( X: 1, 2, 3, 4, 5 \)
- \( P(X): 0, 0.1, 0.2, 0.3, 0.4 \)
