a. P(C|A)=

b. P(D|B)=

c. P(A∩C)=

d. P(B∩D)=

e. P(C)=

f. P(D)=

Answer 1

\[P(A\cap C)=.6\times .8\]
\[P(A)=.6\] and \[P(C|A)=\frac{P(A\cap C)}{P(A)}\]

Answer 2

which is actually a very silly way to do this,

Answer 3

since \(P(C|A)\) is the \(.8\) right in the diagram

Answer 4

i found everything except for e and f

Answer 5

i got it thanks
