There are 6 red marbles, 8 blue marbles, and 11 green marbles in a bag. What is the probability that you will randomly draw either a red or a blue marble?

Hey there! :D

Add the whole amount of marbles together.

6+8+11= 25

Since we are looking for the probability of drawing red or blue, we should add those together.

6+8= 14

We now have this fraction:


(14)/(25)

Divide 14 by 25.

14/25= .56

As a percentage, that is 56%.

I hope this helps!

Total marbles = 6 + 8 + 11 = 25
Total red or blue marbles = 6 + 8 = 14

P(either a red or blue) = 14/25

Change it to percentage = 14/25 x 100 = 56%

Answer: 56%
