Question

Tammy's mom is baking cookies for a bake sale. Currently, there are 22 chocolate chip cookies, 18 sugar cookies, and 15 oatmeal cookies on the counter. Tammy sneaks into the kitchen, grabs a cookie at random, and eats it. Five minutes later, she does the same thing with another cookie. What is the probability that neither of the cookies is a chocolate chip cookie?

Answer 1

So you want 2 consecutive non-chocolate cookies, there are 33 out of the total of 55 cookies
prob of that = (33/55)(32/54) = 16/45
