  1. 16 socks, 6 red so 6/16
    then
    15 socks 5 red so 5/15
    so
    6/16 * 5/15 = 3/8 * 1/3 = 1/8

  4. okay so on quizzes it says the right answer is 3/40 and also I understand what you mean for the most part except for why you multiplied 3/8 by 1/3

  5. a coin is tossed and then the spinner is spun. determine the probability that you toss heads and spin a red. i got 5/6 but that is not an option neither is it reduced or as a prcentage.
