Answer: The option B. 1.9 is correct

Explanation:

We are given the below information:

x               Probability P(x)

0                      0.2

1                       0.1

2                      0.4

3                       0.2

4                       0.1

The expected value of x is given below:

E(x)=\sum x P(x)

         =(0 \times 0.2)+(1 \times 0.1)+(2 \times 0.4)+(3 \times 0.2)+(4 \times 0.1)

        =0+0.1+0.8+0.6+0.4

        =1.9

Therefore, the expected value of x is 1.9
