Probability of Selecting Green Balls

In a bag, there are 5 red balls, 3 blue balls, and 2 green balls. If you randomly select 3 balls from the bag without replacement, what is the probability that at least one of the selected balls is green?

To solve this problem, it will be easier to calculate the probability of the complementary event (the event that no green balls are selected) and then subtract that probability from 1.
