Best ResponseYou've already chosen the best response.0perhaps the answer is \[\dbinom{13}{4}\times \dbinom{39}{1}\times 4\]?

Best ResponseYou've already chosen the best response.0well maybe it means how many possible hand have 4 of one suit and two of another. if so, lets start with clubs. you need 4 clubs and 1 non club. the number of ways to get 4 clubs is \[\dbinom{13}{4}\] and the number of ways you can choose one nonclub is \[\dbinom{39}{1}\]

Best ResponseYou've already chosen the best response.0then we do the same for each other suit hence multiply by 4

Best ResponseYou've already chosen the best response.0my theory is 4(13 C4* 39C1)
