Nicole pulls a colored marble out of a bowl, choosing the marble at random there are 120 marbles in a bowl of which 80 or black and 28 or white and the rest are red use words and numbers to describe the probability that she will pull a red marble out of the bowl show your work
The probability of Nicole pulling a red marble out of the bowl can be calculated by dividing the number of red marbles by the total number of marbles in the bowl.
Number of red marbles = 120 - 80 - 28 = 12
Total number of marbles = 120
The probability of pulling a red marble = Number of red marbles / Total number of marbles
= 12 / 120
= 1 / 10
= 0.1
Therefore, the probability that Nicole will pull a red marble out of the bowl is 0.1 or 10%.
