a fair six-sided die, with sides numbered 1,1,2,3,4,5 is thrown. find the mean and variance of the score?

Question

datanewb · Answer

Well first you should find the mean, as the mean is used to calculate the variance.

The mean is the average, and it is calculated by adding all of the possible scores by the total number of scores.
