Assume that you guess the answers to six questions.
1. Using the multiplication rule to find the probability that the first two guesses are wrong and the last four are correct. Find P(WWCCCC).
2. Beginning with WWCCCC, make a complete list of the differnet possible arrangements of two wrong answers and four correct answers, then find the probability for each entry in that list.
3. Based on the preceeding results, what is the probability of gettting exactly four correct answers when six guess are made?
