(a) Given that two events, A and B, are such that P(A and B) P(A) x P(B), state what you can say about the events A and B. If event A is 'obtaining a 6 on a single throw of a die', suggest a possible description for event B.

(b) Given that two events, C and D, are such that P(C or D) = P(C) + P(D), state what you can say about the two events Cand D. Write down the value of P(C and D). (C)
