In this question, you're trying to find the unit rate in which the teacher can grade tests.
A unit rate is another word for "rate of change".
This means that we have to find how many tests the teacher could grade in 1 minute.
To find the unit rate, divide 18 by 15
18 ÷ 15 = 1.2
This means that Mr. Rivera can grade 1.2 tests in 1 minute.

You could say the probability of not rolling a three is 5/6, because there are six possible outcomes (getting a 1, 2, 3, 4, 5, or a 6), and there are five other numbers besides three, making the probability of not getting a three 5/6.
The answer is option B. Hope this helps:)
