Let P(E) = 0.35, P(F) = 0.3, and P(E ∩ F) = 0.15. Draw a Venn diagram and find the conditional probabilities. 


    (a)  P(F | E ∩ F) = P(F ∩ E)/P(E ∩ F) =  = 1.
 
 

    (b)  P(EC | E ) = P(EC ∩ E)/P(E) =  = 0.


You do not need Venn diagram to solve this problem.

All you need is to know the basic definitions.
