Question

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

What is the probability that the chosen marble is green?

A. 1/18

B. 1/8

C. 1/3

D. 4/9

Answer 1

There are 18 marbles in total and 8 green marbles. 8 out 18 of the possibilities will be green so it's 8/18 = 4/9.

probability is (desired outcomes)/(total possible outcomes)

green:8
total possible=total
4+6+8=18 total

probablity=8/18=4/9

answer is D
