There are two identical boxes containing respectively 4 white and 3 red balls, and 3 white and 7 red balls. A box is chosen at random and a ball is drawn from it. Find the probability that the ball is white.

Consider two boxes, say box A and box B. Suppose that box A contains 60 red balls and 40 white balls while box B contains 30 red balls and 70 white balls. Suppose that a balanced die is tossed once. Let's draw two balls from the box. If the number on the die is one or two, we select from box A and if it is three, four, five, or six, then we select from box B. We select 2 balls at random with replacement. Find the probability that both of the two balls selected are red. (a) 11/25 (b) 2/5 (c) 9/50 (d) 2/3 (e) None of the above
