And the variance would be given by:

And the deviation would be:

4)

And the variance would be given by:

And the deviation would be:

Step-by-step explanation:

For this case we have the following distributions given:

Probability  M   J

0.3           14%  22%

0.4           10%    4%

0.3           19%    12%

Part 1

The expected value is given by this formula:

And replacing we got:

Part 2

Part 3

We can calculate the second moment first with the following formula:

And the variance would be given by:

And the deviation would be:

Part 4

We can calculate the second moment first with the following formula:

And the variance would be given by:

And the deviation would be:

5

step-by-step explanation:

the answer would be 44.79
