I have this question regarding set theory and probability that i am struggling on:

Q: A group of international students take part in a survey on the nationality of their parents.

E= English Parent

F= French parent

n(ξ) = 50, n(E) = 15, n(F )= 9, n(E U F)' = 33

**(1) Find n(E ∩ F) **

** (2) Find n(E' U F)**

** (3) A student is chosen at random. Find the probability that this student has an English parent and a French parent.**

**(4) A student who has a French parent is chosen at random. Find the probability that this student also has an English parent.**
