Question

math expectation of a numerical sum

Answer 1

A total.

Answer 2

A fair die is rolled 10 times. Find the math expectation of the numerical sum
of the outcomes.

Answer 3

This will take surely a lot of time

Answer 4

yes it does

Answer 5

Can u list the possible sums at first.

Answer 6

10,11,12,...,36

Answer 7

Now, u need to make a probability distribution TABLE( which will take too much time)

Answer 8

Then calculate the EXPECTED MEAN.

Answer 9

why till 36?

Answer 10

Maximum possible sum =10*6=60

Answer 11

Oh sorry its 60

Answer 12

yeah

Answer 13

The expected value on one throw is the mean of the numbers 1, 2, 3, 4, 5 and 6 = 3.5.
With ten rolls the expected numerical sum of the outcomes = 3.5 * 10 = 35

Answer 14

I guess @kropot72 is very correct
