Consider 3 scenarios:
(1) all 3 the same colour... 3 options
(2) all 3 different colours... 1 option
(3) 2 of 1 colour and 1 of another colour (so we're using 2 of the 3 colours): 3C2 gives us the possible 2 colour choices. However, we need to double it, since if we choose R and B we could have RRB or RBB.
So, 3C2 * 2 = 3 * 2 = 6
3 + 1 + 6 = 10 possibilities.
