Three freshmen, 3 sophomores, 3 juniors, and 3 seniors are participating on the debate team. The team's captain is randomly selected from any grade level. What is the probability that a freshman will NOT be selected as captain?
There are a total of 12 students on the debate team, and 3 of them are freshmen.
Therefore, the probability of selecting a freshman as captain is 3/12 = 1/4.
The probability of NOT selecting a freshman as captain can be calculated by subtracting the probability of selecting a freshman from 1:
1 - 1/4 = 3/4
So, the probability that a freshman will NOT be selected as captain is 3/4.
