Answer

A: {A 3 appears on each of the two dice.6} A : (3,3) P(A) = 136 B: {The sum of the numbers is even.} Sample points in B = 16 and each is equally likely, so P(B) = 18/36 = 1/2 C: {The sum of the numbers is equal to 7.} Sample points in C = 6 and each is equally likely, so P(C) = 6/36 = 1/6 D: {A 5 appears on at least one of the dice.} Sample points in D = 11 and each is equally likely, so P(D) = 11/36 E: {The sum of the numbers is 10 or more.} Sample points in E = 6 and each is equally likely, so P(D) = 6/36 = 1/6
