In a group of 39 students, 14 study both Art and Biology.
12 study Biology but not Art.
2 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?

If you drew a Venn diagram with art, both and biology you'd get: Art only - 11 students, Bio only - 12 students, Both - 14 students, outside - 2. The probability of a randomly selected art student also studying biology would be 14/25. 25 being the total art students and 14 being the proportion of which also study biology.
