Twenty-five volunteers will wear one of 6 blue, 7 green, 8 yellow, and 4 red aprons during an upcoming food drive. If the aprons are assigned randomly, what is the probability that a volunteer is assigned an apron that is NOT green?
A. 625
B. 725
C. 825
D. 1825
To find the probability that a volunteer is assigned an apron that is not green, we first need to calculate the total number of possible outcomes.
There are 6 + 7 + 8 + 4 = 25 aprons in total.
The number of outcomes where a volunteer is assigned a green apron is 7 out of 25.
Therefore, the number of outcomes where a volunteer is assigned an apron that is not green is 25 - 7 = 18.
The probability that a volunteer is assigned an apron that is not green is 18 / 25 = 0.72 or 72%.
Therefore, the answer is B. 725.
