Question

In a group of 44 students, 11 study both Art and Biology.

10 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?

Answer 1

Number of student that study Art but not Biology = 44 - 11 - 10 - 2 = 21 students

Number of student that study Art = 21 + 11 = 32 students

Probability that the student study Art and Biology = 11 / 32
