The cards are thoroughly reshuffled, and you again choose a card at random, observe its color, and replace it in the set. This process is repeated until you get a red card with X denoting the number of draws required. The random variable X has which of the following probability distributions?
the binomial distribution, with parameters n = 26 and p = 0.5
the binomial distribution, with parameters n = 52 and p = 0.5
None of the above
the binomial distribution, with parameters n = 26 and p = 0.5
