A die is tossed twice. A is the event 'the sumof the two numbers uppermost is greater than 5', B the event 'the sum of the two numbers uppermost is less than 8'. Find the probability of these events:
(a) A
(b) B
(c) AB
(d) A U B
Hence show that P(A U B)=P(A)+P(B)-P(A ^ B).
Are A and B mutually exclusive?
