A) 1 / 12

B) 1 / 6

C) 1 / 3

D) 1 / 2

c) 1/3

Step-by-step explanation:

First, identify what you know:

1) There is a bag of 18 marbles.

2) 6 of them are red.

3) 6 of them are purple.

4) 6 of them are yellow.

Since, each color makes up 1/3 of the bag, then you will only have 1/3 (33.3%) chance of choosing any single color.
