Question

A bag contains 4 red marbles, 6 blue marbles, and 8 green marbles. One marble is to be chosen at random.

What is the probability that the chosen marble will be green?

A. 1/18


B. 1/8


C. 1/3


D. 4/9

Answer 1

4 red marbles
6 blue marbles
8 green marbles

Add:

4 + 6 = 10
10 + 8 = 18
18 total marbles

Green marbles/total marbles

8/18

Simplify:

8 ÷ 2 = 4
18 ÷ 2 = 9
Simplest form = 4/9

8/18 = 4/9
D. 4/9
