    A hypothetical population consists of eight individuals ages 14,15,17,20,26,27,28, and 30 years. What is the probability of selecting a participant who is at least 20 years old?

    At least 20 means 20 or older, so our selection of individuals is:
    {20, 26, 27, 28, 30}

    This is 5 out of a possible 8, so we have 5/8 of 0.625, which is 62.5%
