NOTE: when you see E it is in place of Sigma! ^ shows a square
Looking at the table, find the mean, variance and SD
X p(x)
0 0.539
1 0.351
2 0.095
3 0.014
4 0.001
5 0
6 0
Mean: 0.587 equation I used: E(x p(x))
Variance: 0.528431 equation I used: E(x^2 p(x))-mean^2
SD: 0.7269325966 equation I used: Square root of variance
