Best ResponseYou've already chosen the best response.2so I guess we have to consider the scenario when occurs on the second throw. when 6 occurs on the first throw we have to discount these arrangements

Best ResponseYou've already chosen the best response.2if 1 is middle number there are 72 ways also if 72 for 2 is 4th so we have 120 + 96 + 72 + 72 = 360
