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!
