    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.
