Selecting balls from a bag.

i have a bag of 6 black balls and 14 white balls. What is the probability of getting 3 black balls out?

An important data is missing: how many balls do You get out in total?...

Kind regards

I addition to the above, we must know how the balls are drawn.
Is it with replacement or without replacement?
