Unformatted text preview: Math 218 Final Examination: Spring 2007 Name (Printed) Student ID Signature (handwritten) Directions. Fill out your name, signature, and student ID number on the lines above; then checkmark the lecture time and discussion time in the space provided below. Do not OPEN the test booklet until instructed to do so. After you are so instructed, make sure all 11 pages are present (not including tables, which are distributed separately). Note that the separately distributed sheet of tables is printed on both sides. On this examination, you may use a calculator and one 81/2 by 11inch sheet of handwritten notes (both sides may be written on). No books or other notes are permitted. When an answer box is provided, copy your answer into that box. Numerical answers should be evaluated to be either decimals or fractions. Numerical answers alone are not sufficient; you MUST indicate how you derived them (show your work). When submitting a numerical answer which is a decimal, give three accurate digits following the decimal point; when submitting a fraction, make sure it’s reduced to lowest terms. Be sure to include the appropriate units (for example, feet, pounds, mph, etc.). All problems are equally weighted ( 10 problems at 20 points each = 200 points total). Check one lecture time: 9:00 MWF (Song) 10:00 MWF (Lin) 10:00 MWF (Song) 11:00 MWF (Lin) 11:00 MWF (Bruck) 12:00 MWF (Lin) 12:00 MWF (Emerson) 1:00 MWF (Mesyan) 1:00 MWF (Emerson) 2:00 MW (Goel) 2:00 MW (Verona) 2:00 MW (Zygouras) Check one TTh discussion time: 8:00 9:00 10:00 11:00 12:00 1:00 2:00 3:00 4:00 Do not write on this page below this line! 1 (20 pts) 6 (20 pts) 2 (20 pts) 7 (20 pts) 3 (20 pts) 8 (20 pts) 4 (20 pts) 9 (20 pts) 5 (20 pts) 10 (20 pts) (100 pts) (100 pts) Total Points 1 2 Problem 1 . A jar full of 15 jellybeans contains 4 red jellybeans, 8 yellow jellybeans and 3 black jellybeans. (a) Jack randomly chooses a jellybean from the jar, eats it, and then randomly chooses another. What is the probability that both jellybeans he chose were yellow? Answer: (b) Referring back to part ( a ) above, what is the probability that both jellybeans Jack chose are the same color?...
