Random Variables
Constructing a Probability Distribution

Suppose a pair of dice is rolled. Let X denote their sum. What are the possible values of of X? Assuming that each of the 36 possible outcomes is equally likely, what is the probability distribution of X? Let E={sum of two die}={2,3,4,5,6,7,8,9,10,11,12}
