Fool's problem of the day,
A panel of eight umpires (A, B, C, D, E, F, G and H) is selected for officiating all the Cricket matches played in 2002. The countries which they represent (belong to) are P, Q, R, S, T, U and V, not necessarily in the same order.
(i) In the panel, B and D only belong to the same country i.e., T, while the others represent different countries.
(ii) A belongs to one of the subcontinent countries i.e., Q or U, while G belongs to the other.
(iii) The match between R and V is officiated by E and H.
(iv) H is does not belong to country P.
Note:- The umpires of the same country as the 2 countries that are playing the match cannot officiate in the match.
\(Q_1\): If a match is played between countries Q and V, then how many different combinations of umpires for that match are possible?
\(Q_2\): If in the above question, it is given that E and H are good friends, and always officiate together in a match, then how many different combinations of umpires are possible for the match between Q and V?

Dont know if I'm way off here, but I think its Q1;(9) and Q2;(0)
