Hello,

Thank you for taking the time to explain permutations and combinations (mathsisfun.com / combinatorics / combinations-permutations.html). I am not very familiar with calculating these, but your explanations have helped a lot. Regarding your example of Combinations with Repetition using the five ice cream flavors, how do I calculate the number of combinations that are possible in cases where some of the boxes of ice cream contain a combination of two flavors and some contain a single flavor (e.g. banana, chocolate/vanilla, lemon, strawberry, fudge/mint)?

Thank you for your time,

M.
