Answer:
17% probability that a randomly selected student smokes.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is your estimate of the probability that a randomly selected student smokes?
This estiamte is the number of smoking students divided by the total number of students.
We have that:
There are 500 students.
85 smoke
So there is an 85/500 = 0.17 = 17% probability that a randomly selected student smokes.
