    No, the given procedure doesn't result in a binomial distribution.

    Step-by-step explanation:

    We can identify if a given procedure results in binomial distribution by observing whether these four conditions are met or not.

    Condition 1: Each observation should be independent, it must not depend on the result of previous observation.

    Condition 2: The probability of success should stay same from trial to trial.

    Condition 3: n is fixed (the number of observations)

    Condition 4: There are only two outcomes success or failure.

    Surveying 2828 people to determine which statistics courses they have taken.

    Condition 3 is satisfied since n is fixed

    Condition 1 is satisfied since each observation is independent

    Condition 4 is not satisfied since there can be more than 2 answers from the people (statistics courses can be many).

    No, the given procedure doesn't result in binomial distribution.

    Step-by-step explanation:

    For any procedure to be a binomial distribution, these below four conditions should be met;

    Condition 1: Each and every observation should be independent from the other observations.

    Condition 2: The probability of success (p) should always be same for each trial.

    Condition 3: Number of trials (n) must be fixed.

    Condition 4: There must be only two outcomes success or failure.

    Now, the procedure given to us is : Surveying 2828 people to determine which statistics courses they have taken.

    In this procedure;

    Condition 1 is satisfied since each observation is independent from other. Condition 3 is satisfied as n is fixed for surveying 2828 people. Condition 4 is not satisfied because there can be more than 2 answers from the people regarding which statistics courses they have taken as there as many statistics courses.
