During his first 20 picks from a bag of marbles, Kai chose 8 yellow marbles, 3 green marbles, and 9 blue marbles. Each time he replaces the marble before selecting another. Which percent is closest to the experimental probability that Kai will choose a green marble for his next pick?
All you have to do for this problem is take 3, over the 20, and then turn into a percent. Your final answer is D. 15%, because if you multiply 3/20 by 5, you get 15/100, which is easier to turn into a percent, leaving you with 15%
