Question

If two events are independent, then:

A. the sum of their probabilities must be equal to one.

B. they must be mutually exclusive.

C. their intersection must be zero.

D. None of the above.

Answer 1

Answer:

D

Step-by-step explanation:

Two events are said to be independent if the occurence of one event does not affect the occurence of the other.

Note:

A. there sum cannot be equal to 1

B. Mutually exclusive events are events with posibility of happening at thesame time

C. When intersection is zero, it means the set is empty, because intersection of an empty set is equal to an empty set

Thus, option D feels most appropriate
