For the following probability distribution: `X :\ \ -4\ \ -3\ -2\ \ -1\ \ 0` `P(X):\ \ 0. 1\ 0. 2\ \ 0. 3\ \ 0. 2\ \ 0. 2` The value of `E(X)` is `0` b. `-1` c. `-2` d. `-1. 8`

Text Solution

Verified by Experts

`E(X)=sum X P(X)`

`=4 times(0.1)+(-3 times 0.2)+(-2 times 0.3)+(-1 times 0.2)+(0 times 0.2)`

`=-0.4-0.6-0.6-0.2=-1.8`
