The expected value is 7.
The expected value is 10.5
The expected value is 20 times.
If a DIE (not dice) is rolled 90 times, the expected value of the sum of the first and second rolls is 7 if you assume that the die is fair. It does not matter how many times you roll the die, as long as it is at least 2.
It is its frequency.
The expected value if you roll a die three times is 3.5.
If it is a fair die then it is impossible to predict. The expected value is 20.
The expected value is 10.5
The expected value is 20 times.

In IPv6 addresses the number FF often appears What is the decimal value of FF?
The expected value of the number of Heads in 1 toss of a fair coin is 0.5. So the expected number of Heads in 10000 tosses of a fair coin is ... 5000!
The expected value is 100*1/18 - 10*17/18 = -170/18 = -85/9
Mode is the value (number) that appears the most.
It is its frequency.
The expected value if you roll a die three times is 3.5.
The expected values were 2 of each value. This differs significantly from what was expected. You could show that the die is most likely not fair by using a chi squared test for goodness of fit.
