(iv) A and C are mutually exclusive
Here,
S = {(x,y): 1 x,y 6}
A = {(2, 1), (2,2), (2,3), (2,4), (2,5), (2,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)}
C = {(1, 1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (3,1), (3,2), (4,1)}
(iv) X and Y are mutually exclusive if and only if X Y =
A C = {(2,1), (2,2), (2,3), (4,1)} ,
Hence, A and B are not mutually exclusive. FALSE
