    The probability is 0.95

    Step-by-step explanation:

    In this question, we are interested in calculating the probability that a randomly selected student of the university recycles at least some of the times

    Mathematically, the probability that student recycles at least some of time = 1 - probability that the student never recycles all the time

    From the question, the probability that the student never recycles all the time = 0.05

    Substituting this into the equation given above;

    Probability that a randomly selected student at the university recycles at least some of the time = 1-0.05 = 0.95
