  2. I would pick Box B because you have a 60% chance of picking a red marble in Box A and you have a 66.6% chance of picking a red marble in Box B.

  3. I agree with Ben
    Box A has 5 marbles, three of which are red
    Therefore the probability of drawing a red from box A is 3/5 = .6
    Box B has three marbles, two of which are red.
    Therefore the probability of drawing a red from box B is 2/3 = .66666666.....
