    Answer:

    \frac{7}{9}

    Step-by-step explanation:

    A probability is the number of desired outcomes divided by the number of total outcomes.

    If a single student is picked at random, what is the probability that they received an A or C?

    Desired outcomes

    Student got an A or C

    8 students received an A

    6 students received a C

    14 total outcomes

    Total outcomes

    8 students received an A

    4 students received a B

    6 students received a C

    18 total outcomes.

    The probability is 14/18 = 7/9.
