Morphology

combination = combine (semi-transparent) = combine + ation

The mathematical sense is related to joining elements but adds a technical constraint (order does not matter) that is not deducible from the base verb alone.

Etymology

Combination comes from the part com- meaning 'together' and the verb combine, and in math it means a choice of items taken 'together' where the order does not matter. So a mathematical combination is simply a group of things chosen as one set.
