Hi!

All of the marbles together will be our denominator.

The number of red marbles will be our numerator.

3/9

Simplify

1/3

The answer is 1/3

Hope this helps! :)

He has a total of 9 marbles, and he has 3 red marbles.

The probability of drawing a red marble is 3/9, or 1/3. That is equal to around 33.33%.

I hope this helps :)
