Answer 1

7/13

Step-by-step explanation:

Probability is (# times specific event occurs) / (# times general event occurs).

Here the specific event is drawing a ball that isn't white - in other words, a ball that is either red or green. There are 4 + 3 = 7 such balls, so the numerator of the probability is 7.

The general event is picking a ball; there are 4 + 6 + 3 = 13 total balls, so that's the denominator.

The probability is then 7/13.

Answer 2

7/13

Step-by-step explanation:

Total balls: 4 + 6 + 3 = 13

P(white) = 6/13

P(not white) = 1 - 6/13 = 7/13
