What does that tell you?
2) P(C|D)=P(C and D)/P(D): so do it.
I have two questions I'm having trouble with...
1. If P(A and B) = 0.08, P(A) = 0.2 and P(B) = 0.4, then events A and B are either mutually exclusive, dpeendent, independent, equal or none of the above?
2. P(C and D) = 0.07, P(C) = 0.4 and P(D) = 0.2, find the probability of C given that D has occurred.
Any help would be appreciated.
