May I ask you a big favor?
I need help.
What I have is:
A bag contains marbles of three different colors with at least three marbles of each color.
Three marbles are randomly selected, without replacement. How many different color combinations are possible?
I tried to use Combinatorial Calculator here:
And I've got : 10
Seems like it is the right answer, because textbook shows me the same..
But I want to understand the way of solving it.
Please show me step by step solution or the formula.
Thanks in advance.
