    Answer:14

    Step-by-step explanation:

    30 students total.

    7 received an a in history.

    13 received an a in math.

    4 received an a in both courses.

    how many students did not receive an a in either course.

    20 total received an a in history or math.

    of these, 4 received an a in history and math.

    those 4 are being counted twice.

    once in history and once in math.

    you need to subtract 4 from the number who got an a in history or an a in math to get a total of 16 students who got an a in history or in math.

    this leaves 30 - 16 = 14 students who did not get an a in either course.

    here's the breakdown.

    14 students did not get an a in either course.

    3 students got an a in history only.

    9 students got an a in math only.

    4 students got an a in both history and math.

    total is 30 students.
