M/S 425-1: Intro. Prob. Quiz: October 22, 2004. Solution The quiz was question 1 from the first mid-term, but with the shoes in the closet set-up from an earlier homework. Remember that the shoes can be thought of as a deck of cards with ten “denominations” (the distinct styles) and two “suits” (left and right). Given this, the question is the same with “ace” replaced by “cowboy boot” and “2 of clubs” replaced with “right sandal”. For more detail on the solutions below, check the solutions to the first mid-term. 1. A closet contains 10 pairs of shoes, in ten distinct styles. Of the styles, one is a pair of sandals, and another is a pair of cowboy boots. Suppose that these shoes are drawn one after another from the closet, being chosen at random at each draw and not replaced. That is, at each draw any of the remaining shoes is chosen with equal likelihood. a) What is the probability that the third shoe pulled from the closet is a cowboy boot? Solution:
