2. Question1 Suppose two dice are tossed and the numbers on the upper faces are observed. Let S denote the set of all possible pairs that can be observed. Define the following subsets of S.
A: the number on the second die is even.
B: the sum of the two numbers is even.
C: at least one number in the pair is odd.
List the elements in A,CC,AnB ,AnBC,AC?B, and ACnC.
3. Answer1 S = { (1,1),(1,2),(1,3),(1,4),(1,5),
(1,6),(2,1),(2,2)….(6,6).
N(S) = 6X6 = 36.
A = {(1,2),(2,2),(3,2),(4,2),(5,2),(6,2),
(1,4),(2,4),(3,4),(4,4),(5,4),(6,4),(1,6),(2,6),
(3,6),(4,6),(5,6),(6,6).
B = {(2,2),(4,2),(6,2),(2,4),(4,4),(6,4),(2,6),(4,6),(6,6).
C = {(1,1),(1,2),(1,3),(1,4),(1,5),(2,1),(2,3),(2,5),(3,1),
(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,5),(5,1),
(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,3),(6,5).
4. CC =S – C ={(2,2),(2,4),(2,6),(4,2),(4,4),(4,6), (6,2),(6,4),(6,6)} AnB = B An BC = A – B ={(1,2),(3,2),(5,2),(1,4),(3,4),(5,4),(1,6), (3,6),(5,6)} AC = {(1,3),(2,3),(3,3),(4,3),(5,3),(6,3),(1,5),(2,5),(3,5), (4,5),(5,5),(6,5),(1,1),(1,2),(1,3),(1,4),(1,5),(1,6)} AC ?B ={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(4,2),(2,2),(6,2), (1,3),(2,3),(3,3),(4,3),(5,3),(6,3),(2,4),(4,4),(6,4),(1,5), (2,5),(3,5),(4,5),(5,5),(6,5),(2,6),(4,6),(6,6)} AC nC= AC
