Question

as students were exiting the student center on campus, Cole took note whether they were listening to headphones. The table shows results that he collected. Based on Cole’s data, what is the probability that a randomly selected student will have headphones in their ears when exiting the student center? express your answer as a fraction.

Answer 1

Given:

The number of students will have headphones in their ears when exiting the student center =35

The number of students will have no headphones in their ears when exiting the student center =40

The total number of students = 35+40=75

The perobability is defined as,

`P=\frac{\text{ Desired outcomes}}{\text{Total outcomes}}`

To find the probability that a randomly selected student will have headphones in their ears when exiting the student center is,

`P=(35)/(75)=(7)/(15)`

Answer: the probability is 7/15.
