Some restaurants display a glass bowl in which customers deposit their business cards, and a drawing is held once a week for a free lunch. suppose you and your friend vanessa each deposit a card in two consecutive weeks. define event a = you win in week 1. event b = vanessa wins in week 1. event c = vanessa wins in week 2. events a and b are dependent events. if you win (event a), then vanessa cannot win (event b cannot happen). in this case, p(b) = 0. if you do not win (a does not happen), it is possible that vanessa could win, so p(b) ≠ 0. notice that events a and b refer to the same random circumstance: the drawing in week 1. events a and c are independent. knowing whether you win in the first week (event a) gives no information about the probability that vanessa wins in the second week (event c). notice that events a and c refer to two different random circumstances: the drawings in separate weeks. select all that apply. (a) which events are dependent? a and c b and c a and b (b) which events are independent? a and b b and c a and c
