Boris is taking a quiz for an online class. for the quiz, the  system randomly assigns  2  high-difficulty questions,  7  moderate-difficulty questions, and  6  low-difficulty questions. what is the probability that boris is  assigned a moderate-difficulty question first?
give your answer as a fraction

Step-by-step explanation:

The probability that Boris is assigned a moderate-difficulty question would be the ratio of number of moderately difficult questions to the number of total questions available.

The quiz consists of 2 high difficulty, 7 moderate difficulty, and 6 low difficulty questions. That is 2 + 7 + 6 = 15 questions in total.

and

the number of moderately difficult questions is 7

Hence the probability would be 7/15
