Since C and D are mutually exclusive events, P(C and D) = 0. Therefore, we can use the formula for the probability of the union of two events:

P(C or D) = P(C) + P(D)

Given that P(C) = 2/11 and P(D) = 6/11, we have:

P(C or D) = (2/11) + (6/11) = 8/11

Therefore, the probability of either event C or event D occurring is 8/11.
