➷ You replace the balls, so the type of probability is independent.

First of all, the probability of getting a red ball is:

5/10 or 1/2

As you can see, the probability of getting a green ball is:

3/10

Lastly, the probability of getting a yellow ball is:

2/10 or 1/5

The sum of all of them added together is always:

10/10, or 1

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
