Discrete Probability - Probability of Sets

Question

Hey guys, I need some help with this problem. So they want us to find a) and b). So I know by definition Probability of B Complement is $1 - P(B)$.

So $P(\overline{B}) = 1 - 0.73 = 0.24$. How can I use this to find $P(\overline{B} \cap C)$?

Answer 1

Hint: a) $$\overline{B}\cap C = C\setminus (B\cap C)$$

So $$P(\overline{B}\cap C) = P(C)-P(B\cap C)=...$$

b) Use formula inclusion/exclusion
