rewrite this please:
The probability of pulling a red marble out of the bowl can be calculated by finding the proportion of red marbles to the total number of marbles in the bowl.
First, we need to determine how many blue marbles are in the bowl. Since there are a total of 140 marbles and 80 are black and 28 are green, the number of blue marbles can be found by subtracting the sum of black and green marbles from the total number of marbles:
140 - (80 + 28) = 32
Therefore, there are 32 blue marbles in the bowl.
The total number of red marbles in the bowl is the remaining number after subtracting the black, green, and blue marbles from the total number of marbles:
140 - (80 + 28 + 32) = 140 - 140 = 0
Since there are no red marbles in the bowl, the probability of Christine pulling a red marble is 0.
To find the probability of pulling a red marble from the bowl, we need to calculate the ratio of red marbles to the total number of marbles.
After determining that there are 32 blue marbles in the bowl, we can find that there are no red marbles left. Therefore, the probability of pulling a red marble is 0 for Christine.
