Question

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?
24%
56%
32%
10%

Answer 1

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: 

$\frac{14}{25}$

Divide 14 by 25. 

14/25= .56

As a percentage, that is 56%. 

I hope this helps!

Answer 2

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%
