Tia Gray · Answer 1

There would be a 7/18 chance.

Step-by-step explanation:

Since we are given that we know they have perfect attendance, we limit the sample size to those with perfect attendance (18). Then for the chance, we use the amount who are also on honor role (7). Now we divide the two numbers.

7/18

Molly Snyder · Answer 2

7/56

Step-by-step explanation:

This is because there are 56 people and seven out of them are on the honor roll and have perfect attendance. You have a seven out of fifty-six chance of choosing them.
