There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.

What is the theoretical probability of randomly drawing either a red marble or a blue marble?

20%
32%
52%
13%
10 POINTS!!!!

Respuesta :

This is a educated guess, I would say 52% because the red and blue marbles combined is 17 and that's higher than green
Okay so it asks the probability of drawing a red or blue marble so we must add those together.

25 marbles in total

8 + 5 = 13

13/25 is our fraction 

13 ÷ 25 = 0.52

0.52 x 100 = 52 (Always multiply it by 100 to get the percentage.)

52%

So therefore, your answer is 52%

I hope this helped. Have a great day!
