Answer: 7 red apples and 3 green apples
Explanation:
Let's say that Mia has x total apples in her bag. The probability of picking out a red apple is 7/10, which means there are 7 red apples out of 10 total apples. We can write this as:
7/10 = 7/x
To solve for x, we can cross-multiply:
7x = 10 * 7
7x = 70
x = 10
So Mia has 10 total apples in her bag. We already know that there are 7 red apples, so the remaining apples must be green. Therefore, Mia has:
7 red apples and 3 green apples.
