Answer:

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
Change them into improper fractions
and then find a common denominator, then minus, add, whatever for each one
52m when m= 105
52(105)
5,460
so you plug in the 105 next to the 52 and you multiply it and get 5,460.
