For exam revision, I was looking over some exam problems and I'm stuck on this current problem.
The question is to draw up a Venn Diagram based on the information given below.
60 adults were surveyed about their movie preferences. 38 liked horror movies, 42 liked comedy movies and 35 liked thrillers. 13 liked all three genres. 25 liked horror and thrillers and 4 only liked horrors. None of the adults liked none of those three genres.
I have filled what is given but I am unsure of what to do next.
