Now we can find the second moment with this formula:
And replacing we got:
The variance would be given by:
And the deviation would be:
Step-by-step explanation:
For this case we have the following distribution given:
X 1 2 7
P(X) 1/5 2/5 2/5
We need to begin finding the mean with this formula:
And replacing we got:
