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 words and numbers to describe the probability that she will pull a red marble out of the bowl. Remember to show your work. (2 points)
The probability of pulling a red marble out of the bowl can be calculated by finding the number of red marbles in the bowl and dividing it by the total number of marbles.
Given that there are 140 marbles in the bowl, and 80 are black, 28 are green, we can calculate the number of blue marbles by subtracting the sum of black and green marbles from the total marbles:
140 - 80 - 28 = 32 blue marbles
Since there are no red marbles mentioned in the question, the probability of pulling a red marble out of the bowl is 0/140 or 0.
Therefore, the probability that Christine will pull a red marble out of the bowl is 0.
