    Answer:

    The random variable X is a discrete random variable.

    Step-by-step explanation:

    Let X = number of surface imperfections on computer chips.

    The probability distribution of the number of surface imperfections on computer chips is:

    X    P (X)

    0    0.09

    1     0.22

    2    0.26

    3    0.20

    4     0.12

    5     0.11

    The random variable X is a discrete random variable.

    This is because a discrete random variable has a finite number of possible values with probability of each value ranging from 0 to 1.
