A jar has 19 marbles and 5 of them are green. You pull 3 marbles without replacement. What is the probability that all are green? Write your answer as a fraction. You do not need to simplify
The probability that all three marbles are green can be calculated as:
(5/19) * (4/18) * (3/17)
This can be simplified as (5*4*3) / (19*18*17) = 60 / 5811
Therefore, the probability is 60/5811.
