    Question

    Peter is a basketball player who over the course of the season is successful with 80% of his free throws to success. During a crucial game, he misses for a moment of his 12 free throws. Is such a performance bad for Peter? We assume that seven throws are independent of each other. (Use table of binomial distribution allowed.)


    1. FALSE: Yes, because he has a 50% chance of missing.
    2. FALSE: Yes, because he has an 80% chance of misthrowing.
    3. TRUE: No, because the probability of seven or more failed throws is 0.0039.

    1. Yes, because he has a 50% chance of mis-throwing: Incorrect
    2. Yes, because he has an 80% chance of mis-throwing: Incorrect
    3. No, because the probability of seven or more failed throws is 0.0039: Correct
