First, we need to find out how many marbles are blue. We know that there are 140 marbles in total, and we already know that 80 are black and 28 are green. So, 140 - 80 - 28 = 32 marbles are blue.
Next, we need to find out the probability of pulling a red marble from the bowl. There are no red marbles mentioned in the bowl, so the probability of pulling a red marble is 0.
Therefore, the probability of Christine pulling a red marble from the bowl is 0.
Christine randomly pulls a marble from a bowl. There are 140 marbles in the bow, of which 80 are black, 28 are green, and the rest are blue. Use the words and numbers to describe the probability that she will pull a red marble out of the bowl. Remember to show your work.
