Question

Example: Suppose that we have three boxes contains balls as:
The first box (A1) has 6 red balls, 6 white balls and 8 green balls.
The second box (A2) has 4 red balls, 8 white balls and 8 green balls.
The third box (A3) has 10 red balls, 4 white balls and 6 green balls.
(1) If a box is chosen at random and a ball drawn, if the ball is red, what is the
probability that it was from first box?
(2) If a box is chosen at random and a ball drawn, if the ball is white, what is the
probability that it was from second box?
(3) If a box is chosen at random and a ball drawn, if the ball is green, what is the
probability that it was from third box?
