A batch of 125 lightbulbs contains 13 that are defective. If you choose 8 at random
(without replacement), what is the probability that
(a) None are defective?
(b) Exactly one is defective?
(c) More than 2 are defective?
whats needed

1) Define a random variable in words. (e.g. X = number of heads observed)
2) Specify the distribution of the random variable including identifying the value(s) of any
parameter(s). (e.g. X ∼ Binomial(10, 5))
3) State the desired probability in terms of your random variable (e.g. P(X < 3)).
4) Calculate the desired probability (e.g. P(X < 3) = .055). [Note: You may need more
than 1 random variable per question.]

For this question, you may (where appropriate) write down an Excel formula using one of the functions listed below instead of providing a numerical answer. However, you must specify clearly the value of each parameter in the Excel function (you may use the 2010 or the 2007 version). If you choose to provide a numerical answer, it should be accurate to 3 significant figures. (a) Let F denote the cumulative distribution function (cdf) of a uniformly distributed random variable X....
