Answer 1

2/5

Explanation:

Answer 2

2/5

Explanation:

In order to find the probabability, you first need to find your total. So:

A, B, C, D,

8+ 6 + 4 + 2 =

20

Since, 20 is out toal it goes in our denominator

Now since we artrying to find the probability of A then we count the number of students who an A and place that in our denominator

8/20

We simplify

2/5
