Since A and B are mutually exclusive events, they cannot occur simultaneously. Therefore, the probability of either A or B occurring is the sum of their individual probabilities:

P(A or B) = P(A) + P(B) = 0.30 + 0.40 = 0.70

Therefore, the probability that either A or B occur is 0.70, which is option C.
