There are a total of 140 marbles in the bowl. Of these, there are 80 black marbles and 28 green marbles. Therefore, the number of blue marbles is calculated by subtracting the number of black and green marbles from the total: 140 - 80 - 28 = 32.
The probability of pulling a red marble out of the bowl is calculated by dividing the number of red marbles by the total number of marbles: 0 / 140 = 0. This means that the probability of Christine pulling a red marble out of the bowl is 0.
rewrite this answer
The total number of marbles in the bowl is 140.
The number of black marbles is 80 and the number of green marbles is 28. Therefore, the number of blue marbles is:
140 - 80 - 28 = 32
The probability of pulling a red marble out of the bowl is:
Number of red marbles / Total number of marbles
= 0 / 140
= 0
Therefore, the probability of Christine pulling a red marble out of the bowl is 0.
