Part I: Probability For each of the following problems, you should write your answer as an expression. Do not give the final numeric value. For example, you should write C(4,2)/24 instead of 0.375. 5. You are playing Scrabble and you draw seven tiles: M, A, T, C, H, E, S. You line them up in some random order on your tile rack (assume all orderings are equally likely). The events M, T, and S are defined as follows: M: The tiles M, A, T, H appear consecutively. T: The tile T appears exactly in the middle (fourth position). S: The tile S is either in the first position or in the final position. Calculate the probability of each event; that is, p(M), p(T), and p(S). 5.1 5.2 What is p(MIT)? 5.3 What is p(MIS)? 5.4 5.5 What is p(T|S)? Consider all pairs of events: (M,T), (M,S), and (T,S). Which pairs of events are independent and which pairs of events are not independent? Justify your answer.

How are your grades? In a recent semester at a local university, 700 students enrolled in both Statistics I and Psychology I. Of these students, 77 got an A in statistics, 68 got an A in psychology, and 35 got an A in both statistics and psychology. Round the answers to four decimal places, as needed. Part 1 of 2 (a) Find the probability that a randomly chosen student got an A in statistics or psychology or both. The probability that a randomly chosen student got an A in statistics or psychology or both is Part 2 of 2 (b) Find the probability that a randomly chosen student did not get an A in psychology. The probability that a randomly chosen student did not get an A in psychology is X X
