Basketball The diagram shows the memberships for the Spanish Club and the Basketball Club. Spanish Note that "Tammy" and "Jessica" are outside the circles since they are not members of either club. One student from the class is randomly selected. Bob Let A denote the event "the student is in the Spanish Club." Elsa Ravi Let B denote the event "the student is in the Basketball Club." Kaitlin Sam Jose Karen Teresa Pablo Tammy Jessica (a) Find the probabilities of the events below. Write each answer as a single fraction. P(A) = 1 X P(B) = 1 P( A or B) = [ P(A and B) = 1 P(A) + P(B) - P(A and B) = [ (b) Select the probability that is equal to P (A) + P(B) -P(A and B).
