Answer 1

Given:

Eric’s business class has 91 students

Mr. Eric randomly chooses one student to collect yesterday’s work

We will find the probability that he selects a female, given that he chooses randomly from only the juniors

As shown from the table:

The number of females from the juniors = 6

The number of juniors = 6 +13 = 19

So, the probability will be =

`(6)/(19)`
