Solution

The correct options are
A A and B are mutually exclusive.
C P(AB)=0
Given the probability of intersection of two events A and B is 0.
That is P(AB)=0
We know that when A and B are two mutually exclusive events that is the occurrence of event A does not affect the occurrence of event B at all, in such a case, P(AB)=0
Therefore A and B are mutually exclusive events and P(AB)=0.
Hence, A and C are correct options.
