6 A die is loaded in such a way that the probability of each face turning up is proportional to the number of dots on that face. (For example, a six is three times as probable as a two.) What is the probability of getting an even number in one throw? ~ 7 Let A and B be events such that P (A B) = 1/4, P (A) = 1/3, and P (B) = 1/2. What is P (A B)? A student must choose one of the subjects, art, geology, or psychology, as an elective. She is equally likely to choose art or psychology and twice as likely to choose geology. What are the respective probabilities that she chooses art, geology, and psychology? 9 A student must choose exactly two out of three electives: art, French, and mathematics.
