    Yes, your question makes no sense, you're saying that exactly 0.40 percent go to the carwash, so out of 13 people, 5.2 will go to the car wash.

    So exactly 7 has a probability of 0
    8 or less has a probability of 1
    6 or more has a probability of 0
    less than 5 has a probability of 0.

    Do you see how the question doesn't make sense?
