Rudy placed 12 red marbles, 11 green marbles, 8 white marbles, 9 marbles of other color, into a bag. He plans to draw a marble from the bag, record its color, then place the marble back into the bag before drawing again. If he does this 50 times, How many times should he expect to draw a marble that is red? Please help! :( I've been trying to slave this all day. This is my last resort.
