To find the probability of pulling a red marble out of the bowl, we need to first determine how many red marbles are in the bowl. Since there are 140 marbles in total and 80 are black, 28 are green, and the rest are blue, we can calculate the number of red marbles by subtracting the sum of the black, green, and blue marbles from the total number of marbles:
140 - 80 - 28 = 32
There are 32 red marbles in the bowl.
Next, we calculate the probability of pulling a red marble by dividing the number of red marbles by the total number of marbles:
Probability = Number of red marbles / Total number of marbles
Probability = 32 / 140
Probability = 0.22857 or 22.857%
Therefore, the probability that Christene will pull a red marble out of the bowl is 22.857%.
140 - 80 - 28 = 32
There are 32 red marbles in the bowl.
Next, we calculate the probability of pulling a red marble by dividing the number of red marbles by the total number of marbles:
Probability = Number of red marbles / Total number of marbles
Probability = 32 / 140
Probability = 0.22857 or 22.857%
Therefore, the probability that Christene will pull a red marble out of the bowl is 22.857%.
