    Conditional Probability

    **I need some help with part (c) of this problem I was able to do (a) and (b). I'm guessing it would be P(1)+P(2) but it doesnt work. Any help would be greatly appreciated.**


    A sample space contains six sample points and events A, B, and C as shown in the Venn diagram. The probablities of the sample points are P(1)=0.25, P(2)=0.5, P(3)=0.05, P(4)=0.05, P(5)=0.1, P(6)=0.05.
    Use the Venn diagram and the probabilities of the sample points to find:
    (a) P(B) =
    (b) P(A|C) =
    (c) P(Bc|A) =

    Apply the usual conditional probability formula to get \displaystyle \frac{P(1) + P(2)}{P(1) + P(2) + P(3)} = ....

    If the questions are specifically related to the problem you posted in this thread, then you can ask them here. Otherwise, start a new thread for your other questions. (The forum rules stuck at the top of each subforum explain this in more detail).
