4 men and 6 women are ranked according to their scores on an exam. Assume that no two scores are alike, and that all 10! possible rankings are equally likely. Let X denote the highest ranking achieved by a man (so X = 1 indicates that a man achieved the highest score on the exam). Find each of the following: 0.2667 P(X = 2) = = P(X= 4) = P(X= 5) = | P(X = 9) = 0

1. On this problem, give exact answers using both fractions and exact decimals. One card is chosen from a set of cards that have ranks 1 to 6. Let X be the number on the card chosen. The distribution function for picking the cards is given as follows: m(1) = 6/100, m(2) = 33/100, m(3) = 11/100, m(4) = 37/100, m(5) = 8/100, m(6) = 5/100. Let E be the event "A card with an odd numbered rank is drawn," and F be the event "A card whose rank is less than or equal to 3 is drawn." (a) Compute P(E). (b) Compute P(F). (c) Before you compute P(Eŉ F), explain (in whole sentences) whether or not it is safe to use the formula P(E^ F) = P(E) · P(F) before knowing the answer to part (g). (d) Compute P(EΜF). (e) Compute P(F|E). (f) Compute P(E|F). (g) Based on some of your answers to parts (a), (b), (e), and (f), explain (in whole sentences) whether events E and F are independent or not.
