12. A set of ten cards consists of five red cards and five black cards. The cards are shuffled thoroughly and I am given the first four cards. I count the number of red cards X in these four cards. The random variable X has which of the following probability distributions? a. The binomial distribution with parameters n = 10 and p = 0.5. b. The binomial distribution with parameters n = 4 and p = 0.5. c. None of the above.
