Question

Suppose there is a bag of 20 marbles. Of these marbles, 12 are green, 5 are blue, 2

are red, and 1 is black. What is the probability of drawing three marbles and having all
three be blue, without replacement?

Answer 1

3/20 or (i think %15)

Explanation

This is mostly a guess since I haven't done probability in a while. Good luck though.
