we have the following data set
x . . . . P(x) . . . . . x*p(x)
0 . . . . 0.15 . . . . . 0
1 . . . . 0.20 . . . . . 0.20
2 . . . . 0.30 . . . . . 0.60
3 . . . . 0.10 . . . . . 0.30
4 . . . . 0.20 . . . . . 0.80
5 . . . . .0.05 . . . . .0.25
adding the third column, we get 2.15
dividing by 15 we get
.14333
