The probability of pulling a red marble is somewhere between 0 and 1. Since there are 80 black marbles and 28 white marbles, that leaves us with 12 red marbles (120 total marbles - 80 black marbles - 28 white marbles). So the probability of pulling a red marble is 12 out of 120, or 1 out of 10. This means there is a 1 in 10 chance of pulling a red marble from the bowl.
