How would I approach this problem?

The Venn diag below shows the 13 students in Ms. Jenkins's class. The diagram shows the memberships for the Chess Club and the Science Club. A student from the class is randomly:r selected. LetA denote the event "the student is in the Chess Club." Let B denote the event "the student is in the Science Club." The outcomes for the event A are listed in the circle on the left. The outcomes for the event B are listed in the circle on the right. Note that Ryan, Yoko, and Heather are outside the circles since they are not members of either club. Heather Chess Trey Jina Bill Christine Maya Science (a) Find the probabilities of the events below. Write each answer as a single fraction. P(4) = 0 P (B) = 1 P ( A and B) = P(B IA) = I P(A).P(B IA) = 1 (b) Select the probability that is equal to P (A and B). OP(B) OP(BA) OP(A).P(B|A) OP(A)
