Acookie jar contains 6 chocolate chip cookies, 4 oatmeal cookies, 8 peanut butter cookies, and 2 sugar cookies. if a cookie is pulled from the jar what is the probability that it is oatmeal or peanut butter? a) 1 5 b) 2 5 c) 3 5 d) 4 5

You have 20 cookies total in the jar.  The probability of choosing an oatmeal is 4/20, and the probability of choosing a peanut butter cookie is 8/20.  In order to find the probability of pulling a peanut butter cookie OR an oatmeal cookie, we have to add the probabilities together.  8/20 + 4/20 = 12/20 or 6/10 or 3/5.  The answer is C.
