# Independent and mutually exclusive events

Select the correct answer and explain briefly why

1. Two mutually exclusive events having positive probabilities are ______________ dependent.

A. Always

B. Sometimes

C. Never

They are necessarily dependent because the occurrence of one (seriously) affects the probability of the other (makes it zero).

2. If P(A)>0 and P(B)>0 and events A and B are independent, then:

A. P(A)=P(B)

B. P((A|B))=P(A)

C. P(A B)=0

D. P(A B)=P(A)/ P(B/A)

E. Both A and C are correct
