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
