Find the value of the cosine for angle a

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?

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1
