Question 134350: bag #1 has 2 marbles, 1 black and 1 red
bag #2 has 5 marbles, 2 black and 3 red
Without seeing into the bag, you may select one marble from either bag. If it is black, you win a prize. Would it be better to select one marble from bag #1, bag 2 or does it make no difference? Answer by oscargut(2103) (Show Source):
