2. A jar contains 6 red, 7 white, and 7 blue marbles. If a marble is chosen at random, find the following probabilities. a. b. c. d. P (red) P (white) P (red or blue) P (red and blue) P(A) = (favorable outcomes) / (total # of outcomes) P(A or B) = P(A U B) = P(A) + P(B) P(A and B) = P(A B) = P(A)*P(B) a. b. c. d. P(red) = (# of red marbles) / (total # of marbles) = 6/20 = 3/10 P(white) = (# of white marbles) / (total # of marbles) = 7/20 P(red or blue) = P(red) + P(blue) = 6/20 + 7/20 = 13/20 P(red and blue) = P(red)*P(blue) = (6/20)(7/20) = 21/200
