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 $P(1)=0.1,$ $P(2)=0.35,$ $P(3)=0.1,$ $P(4)=0.25,$ $P(5)=0.15,$ $P(6)=0.05.$
Use the Venn diagram and the probabilities of the sample points to find:
(a) $P(\overline{A})$ $=$
(b) $P(B|A)$ $=$
(c) $P(C|\overline{A})$ $=$
