Age (years) Number of students (f)
Under 21 409
21-25 409
26-30 204
31-35 60

A student from the community college is selected ar random. Find the probability that the student is between 26 and 35 inclusive.

Answer 1

0.2391 = 23.91% probability that the student is between 26 and 35 inclusive.

Explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

409 + 409 + 204 + 60 + 22 = 1104 students, in total

204 + 60 = 264 between 26 and 35.

264/1104 = 0.2391

0.2391 = 23.91% probability that the student is between 26 and 35 inclusive.
