If x equals the number of red marbles drawn which of the following tables shows 3545377. 1 2 chance we pick jar a 50 50 chance we pick a red marble 1 2 chance we pick jar b 0 50 chance we pick a red marble. So the probability of white is 5 11.

So the probability of drawing red is 3 12 or 1 4 reduced. The probability of both happening would be 1 4 x 12 47.
