**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) =
