100 points, hi, i’m not sure how to get the equation from the graph and table.

There are three bags: a (contains 2 white and 4 red balls), b (8 white, 4 red) and c (1 white 3 red). you select one ball at random from each bag, observe that exactly two are white, but forget which ball came from which bag. what is the probability that you selected a white ball from bag a?

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).
