You have a kerplunk game in which a marble will fall out of a certain hole 26% of the time. You decide to drop 8 marbles in the game one at a time and observe which hole the marble goes through. A) Find the probability that exactly two of the marbles will fall out of the game through the hole. B) If we let X be the number of marbles that fall through the certain hole, then find Ux and 02x. That is to say, find the mean and variance.
