Answer 1

40%

Explanation:

We Know

A bag of cotton has 10 red marbles and 15 green marbles.

10 + 15 = 25 marbles total

If you can use Lexi marble from the bag without looking, what is the probability that she will pull out a red marble?

We Take

(10 ÷ 25) x 100 = 40%

So, the probably that she will pull out a red marble is 40%
