The probabilities of four events A, B, C and D obtained from an experiment are recorded below:
P(A)=0.18,P(B)=0.27,P(C)=0.32,P(D)=0.26
(i) Verify whether the recorded probabilities constitute a valid set.
(ii) If they are not valid, assuming the values of A, B and C are correct, determine the correct probability of event D so that the set becomes valid.
