Hello,

I'm trying to figure out this probability problem. Can anyone help walk me through? Thank you so much!!

A box contains 10 green, 2 red, 7 yellow, and 6 blue marbles. Four marbles are drawn from the box without replacement.
a) What is the probability that all four marbles are the same color?
b) What is the probability that none of the marbles is yellow?
c) What is the probability that you get one marble of each color?

What is your thinking on this? We will be happy to check that.
