    Note this question is a bit tricky/misleading as not all the dots are displayed for the 300  students.

    Only 20 (instead of 30) dots are displayed. The remaining 10 dots that exist outside of the two circles are not displayed.

    With this in mind:

    1) # of students under 30 = those 4 dots on the right
    2) # HS graduates = those 11 dots on the left (not counting the overlapping middle region)
    3) Both under 30 & HS graduate = those missing 10 dots that are not displayed outside of the 2 circles.

    4+11+10 = 25

    Since there should be a total of 30 dots, you would do 25 / 30 = 5/6

    Alternatively, you can recognize this as the opposite of all the regions mentioned is simply the overlapping region in the region. It's easier to count that as 5 dots.

    Since there are 30 total dots, you would do 30-5 = 25 and divide that by the total 30 dots.

    That gets you 25/30 = 5/6

    The answer to Question 2 is actually "C. 1 out of 3"

    The magazine version of the article shows the correct answer, but the online version of the article does not.  (As of the time I am posting this note, the online article gives the incorrect answer for Question 2 of "B. 2 out of 3").
