What is the probability that at least one of the stocks will rise in price?

Are eventsAandBmutually exclusive?

a. Yes becauseP(A|B) =P(A).

b. Yes becauseP(AB) = 0.

c. No becauseP(A|B) P(A).

d. No becauseP(AB) 0.

Are eventsAandBindependent?

a. Yes becauseP(A|B) =P(A).

b. Yes becauseP(AB) = 0.

c. No becauseP(A|B) P(A).

d. No becauseP(AB) 0.
