How so? Kronos is essentially adding (G and H hit), (G and K hit) and (H and K hit). I don’t see ?how (G, H and K) hit has been counted thrice in that approach.

“G and H hit” itself comprises two sub-cases (“G and H hit and K also hits” which is G*H*K, and “G and H hit but K misses” which is G*H*(1-K)). The former is common to all the three!

hey J …In the 4th question, why do we take complement of the person….what is wrong with G*H+G*K+H*K?

You could do that, but then you would need to subtract G*H*K 3 times as you have counted it in each of those three.
