On a tray there are 11 sugar cookies,14 chocolate chip cookies,16 oatmeal raisin cookies, and 12 peanut butter cookies. if shaina picks one cookie at random, what is the probability that it is not a sugar cookie

The answer would be A. because in order to find probability, you need to add up all the numbers. So, in this case you would add up 11 +14+ 16+ 12 which would equal 53. So, now 53 is the denominator. Now, to find the numerator, all you have to do is 53 - 12 which is the number of sugar cookies. The answer therefore is 42 over 53! Hopefully that helped!
