A)  therre are 13 clubs in 52 cards so the probability of drawing a club is 1/4.  Since there are four independent decks involved here the probability of all four drawing a club is (1/4)4, or 1/256

 

B).  There are 26 red cards in a deck, so probability of drawing one is 26/52 or 1/2

      There are 4 kings in a deck, so probability of drawing one is 4/52 or 1/13

      There are 26 black cards, so probability of drawing one is 1/2

      There is only one 2 of clubs so probability of drawing it is 1/52

Overall probability is obtained by multiplying these together, namely:  (1/2)*(1/13)*(1/2)*(1/52) or 1/2704

 

C) Try this one yourself using a similar sort of reasoning.
