    Question Statistics, need help in Probabilities

    I am stuck on the following question...please help

    Joe Smith batted .347 in 2007. So assume the probability of getting a hit is .347 for each time he batted. In a particular game he batted three times.

    a. This is an example of what type of probability?

    b. What is the probability of not getting any hits in a game?

    c. What is the probability of getting at least one hit?

    If you know the answer to a. you should be able to do b. and c.

    Let X be the random variable number of hits each time he bats.
    X ~ Binomial(n = 3, p = 0.347) (why?).

    b. Find Pr(X = 0).

    c. Find \Pr(X \geq 1) = 1 - \Pr(X = 0).
