A) You Are Buying a Holiday Gift for Each of Five

A) You are buying a holiday gift for each of five young nieces/nephews. You have found eight different books at one store that would be good choices for any of the children. In how many ways can you buy five of the eight books?
B) Now you are ready to wrap the books. You have six different kinds of paper and four kinds of ribbon. You decide to use a different paper-ribbon combination for each book. In how many ways could one of the presents be wrapped?
C) You also buy a chocolate star, a chocolate snowman, a chocolate candle, a peppermint cane, and a jelly-bean tree. You decide to give one candy each to the five children. Knowing that only one of the five children does not like chocolate, in how many ways can you assign the candies to the five children?
