    Answer:

    The sum of the probabilities of all possible outcomes is not 1, which means that a probability distribution is not given.

    Step-by-step explanation:

    We are given these following probabilities:

    P(X = 0) = 0.6591

    P(X = 1) = 0.2872

    P(X = 2) = 0.0503

    P(X = 3) = 0.0044

    P(X = 4) = 0.0015

    Determine whether a probability distribution is given.

    We have to see if the sum of the probabilities of all possible outcomes is 1. So

    0.6591 + 0.2872 + 0.0503 + 0.0044 + 0.0015 = 1.0025

    The sum of the probabilities of all possible outcomes is not 1, which means that a probability distribution is not given.
