Question

Theirs 165 freshman145 Sophomores 114 Juniors102 SeniorsIf a studemt is chosen at random from this group whats the probability a senior will be chosen

Answer 1

To find the probability of choosing a senior student, we have to divide the total number of seniors by the total number of students.

According to the problem, there are 102 seniors. Let's sum to find the total number of students.

`165+145+114+102=526`

Then, we divide these numbers.

`P_{\text{senior}}=(102)/(526)=(51)/(263)\approx0.19`

The probability of choosing a senior is 51/263 or 19%, approximately.
