Question

During his first 20 picks from a bag of marbles, Mark chose 8 yellow marbles, 9 green marbles, and 3 blue marbles. What is the experimental probability that Mark will choose a green marble on his next pick?

please show work

Answer 1

to solve this problem you have to take 9 over 20 (by assuming replacing the marbles)

9/20 is the experimental probability for a green marble to be picked

9/20 = 45%
