We can have 4 packages of same size with same colours and since we have 2 sizes then this yields 8.
then selecting 3 out of 4 in 4 ways and since we have 2 sizes again we have 8 options.
IMO it is 16

Yes, 16 it is
(1) all same color: 4 possibilities: BBB, GGG, YYY, PPP. 2 sizes, so total 8
(2) all different colors: 4C3 combinations for 1 size = 4. For the 2 sizes., 8
And that marks my 100 th post!
