Given the following information about events B and C:
P(B)=70%
P(B AND C)=0
P(C)=45%
Are B and C mutually exclusive, independent, both, or neither?
Perfect. Your hard work is paying off 😀
B and C are both mutually exclusive and independent because P(B AND C)=0
B and C are independent because P(B AND C)=0
B and C are mutually exclusive because P(B AND C)=0.
B and C are neither mutually exclusive nor independent.
Answer Explanation
Correct answer:
B and C are mutually exclusive because P(B AND C)=0.
Since P(B AND C)=0, we can conclude that B and C are mutually exclusive. P(B AND C)≠P(B)⋅P(C), so we cannot conclude that the events are independent.
