Answer 7

yea me too, i was shocked lol, i wasnt trying to bully

Answer 8

if one of the list contained 3 T's then drop that list, but I dont see any such list above, I see either 1 or 2 T's and either 3 or 2 H's, so the answer in my opinion is all 4 lists are the answer

Answer 9

just saw 4 H's as well i.e Zero T's, so am sorry, you need to drop that list because we r looking for only 2 and 3 H's but NOT 4 H's
