HELP PLS HERE IS IT NEED IT

Answer 1

0.86

Explanation:

We want to find the probability that a student earns a grade of A, B or C.

Total frequency for A, B & C = 5 + 10 + 15 = 30

There are a total of 35 students overall for the geometry course.

So,

P(A, B or C) = 30/35

P(A, B or C) = 6/7 or 0.8571

now we round to the hundredths place

0.8571 ⇒ 0.86

Answer 2

Explanation:

Total students = 35

Probability that a student earns A B or C = 5 + 10 + 15 = 30

35/30 = 7/6
