Question

If a bag contains 4 red marbles, 7 green marbles, 9 yellow marbles, and 2 black marbles. If you randomly draw a marble from the bag. What is the probability that you will draw a red or green marble?
A. 11/25
B.1/2
C.2/11
D.1/4
E.7/22

Answer 1

I think that it would be B). 1/2

The reason I think that is because if you add all the marbles up you get 22. Then if you add the red and the green marbles you get 11. 11 is half of 22 making it a 50% chance. 1/2 is the same as 50% or a half.

Answer 2

I think it would be E 7/22..... there are 22 marbles total, so chances of drawing a red or green would be 7.
