Find the expected value of the following probability distribution.
| Outcome | -5 | -3 | -1 | 1 | 3 | 5 |
| Probability | 0.04 | 0.06 | 0.11 | 0.11 | 0.22 | 0.46 |
Solution :
expected value =
X * P(X)
= -5 *0.04 + -3 * 0.06 + -1 * 0.11 + 1 *0.11 + 3 *0.22+5*0.46
= ( -0.2+ -0.18 +-0.11 +0.11+0..66+2.3 )
expected value = 2.58
