I didnt understand ...

if there should be two from each box , the total number shoukdnt be EVEN??

Posted from my mobile device

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.
