1. Roll two fair dice. Let X1 = value on the first die and let X2 = value on the second die. For each of the variables below, find the expected value and the variance of the variable. Note: in HW 3 you found the pmf and cdf of these random variables. a) Y= X1 + X2, the sum of the scores b) U= min{X1,X2} , the minimum score c) V= max{X1,X2}, the maximum score
