Question

You have a bag full of 17 marbles. Of those marbles, 3 are black. What is the probability that a marble chosen is not black? A. 1/3 B. 1/17 C. 14/17 D. 3/17

Answer 1

C. 14/17

17-3=14
There are 14 non-black marbles.

14/17

Answer 2

C.: The answer is C because the probability that the marble chosen WILL be black is choice D: 3/17. However, the question is asking what the probability is that a marble chosen is NOT black. Therefore, you do 17-3 and get 14. So, the answer is 14/17: C.
