Question

I'm doing a study guide for my next math quiz and I need help on how to solve two questions:
A group of students were surveyed to find out if they like chicken or beef. The results of the survey are shown below:

60 students like chicken
10 students like chicken but do not like beef
80 students like beef
50 students do not like chicken

Part A: What percentage of the total students surveyed like both chicken and beef?
Part B: What is the probability that a student who does not like chicken also does not like beef?

Answer 1

10 like chicken but not beef.
