Answer 2

Given - Probability of students in uniform

Find - Probability that students are not in uniform

Solution - The probability that students are not in uniform is 7/30.

The sum of probability of an event and probability of not an event is 1.

So, the probability of an event is the probability that students are in uniform in this case.

The probability of not an event, in this case, is the probability that students are not in uniform.

Keeping the values in the formula to find the probability that students are not in uniform.

23/20 + Probability that students are not in uniform = 1

The probability that the students are not in uniform = 1 - 23/30

The probability that students are not in uniform = 30 - 23/30

The probability that students are not in uniform = 7/30

Hence, the probability that students are not in uniform is 7/30.
