At least two means 2,3,4,5 etc, so not just even.
12 tablets = 12 B but no A
17 tablets = 15 B and 2 A (even if 15 B extracted)
pick 12 tablets out of the box, chances are that all the 12 tablets are B.
so we have 12 B tablets, not at least two of each kind.
but if we pick 17 tablets out of the box, then even after 15 B we can still have 2 tablets of A.
i mean pick 17 then you have to pick at least 2 from A as well as at least 2 from B.
