Solution :
x | P(x) | x * P(x) | x2 P(x) |
1 | 0.361 | 0.361 | 0.361 |
2 | 0.427 | 0.854 | 1.708 |
2 | 0.188 | 0.376 | 0.752 |
3 | 0.024 | 0.072 | 0.216 |
Sum | 1 | 1.663 | 3.037 |
The sum of the probability is equal to 1 .
P(X) = 1
Yes the table shows the probability distribution .,
Mean = = X * P(X) = 1.7
Standard deviation =
=X 2 * P(X) - 2
= 3.037 - 1.6632
= 0.5
