Use the following for Q1 and Q3. Suppose the probability a student from a large university smokes cigarettes is 0.22 and the probability a student is an international student is 0.19. The chance a student from the same university smokes cigarettes and is also an international student is 0.08. Q1. (1 point) Given a randomly student is an international student, what is the probability they are also a smoker? Q2. (1 point) Given a randomly student is smoker, what is the probability they are an international student? Q3.(I point) Are the events being a smoker and international student independent at this university? Why?
