There are 3 Boxes having the following compositions of black and white balls. Box I: 6 white, 4 black balls; Box II: 3 white, 7 black balls; Box III: 2 white, 8 black balls. One of these boxes is chosen at random with probabilities 0.30, 0.50, and 0.20, respectively. From the chosen box, two balls are drawn without replacement. Then (i) Calculate the probabilities that both balls are white. (ii) What is the probability that both the balls selected from Box II?
