A bag contains 2 red balls and 18 green balls. A ball is chosen at random from the bag. What is the BEST answer for the probability of drawing a green ball?
There are 20 total balls in the bag, and 18 of these 20 balls are green. Therefore, the probabability of choosing a green ball is 18/20, which simplifies to 9/10 (if you divide both the numerator and denominator by the greatest common factor of 2).
