The probability to randomly draw a marble is 20c1 the probability to draw a white marble from 10 white marbles is 10c1 thus the probability to draw a white marble out of 20 is. So the probability of drawing red is 3 12 or 1 4 reduced. 4 red 6 white and 10 blue. A jar contains nine blue marbles eight yellow marbles 11 black marbles and 12 red marbles.
