1). If two events A and B are collectively exhaustive, then A is the ...................... of B.

A. Compliment 

B. Conditional probability 

C. Inverse 

D. Reciprocal

💡

The correct answer is A. Complement.

If two events, A and B, are collectively exhaustive, it means that one of the events must occur. In other words, the union of events A and B covers all possible outcomes. 

The complement of an event represents all the outcomes that are not part of that event. Therefore, if A and B are collectively exhaustive, the complement of event A would include all the outcomes that are part of event B.
