A fair, six-sided die is rolled. Describe the sample space S, identify each of the following events with a subset of S and compute its probability (an outcome is the number of dots that show up). S = {1, 2, 3, 4, 5, 6} A. A = {2, 4, 6} P(A) = B.B = P(B) = C. A’ = P(A’) = D.P(A | B) = E. P(B| A) = F. A ∩ B+ G=P(A ∩ B) = H. A ∪B= P(A ∪ B) = I. P(A ∪B′)= A = {2. 4. 6} B = {1, 2, 3} B’ = {4, 5, 6}
