In how many ways 13 cards to each 4 players to be distributed from a pack of 52 cards and that each may have
A) Ace, King, Queen, Jack of same suit
B) Ace, King, Queen, Jack of any suit
Solution
A) For the first part, firstly, we will choose the suit to distribute to each player and then calculate the number of ways to distribute them. Then we will distribute remaining cards to all of them.
B) For the second part, we will choose ace, king, queen and jack to distribute to each player. Then we will distribute remaining cards to all of them.
Complete step-by-step answer:
A) Number of ways of choosing a suit from 4 different suits =4C1
Number of ways to arrange these 4 different suits =4!
Now, the number of ways to distribute remaining 48 card to 4 groups is
=12!×12!×12!×12!48!
So total number of ways to distribute according the first condition is
=4C1×4!×12!×12!×12!×12!48!
=4×4!×12!×12!×12!×12!48!
So our answer is =4×4!×12!×12!×12!×12!48!
B) For first player, we chose one of ace, jack, king or queen
For second player, we chose in the same way and similarly for third and fourth player
So ways for this =4×4×4×4=(4)4
Number of ways to arrange these distributions to all four players =4!
Now, the number of ways to distribute remaining 48 card to 4 groups is
=12!×12!×12!×12!48!
So total number of ways to distribute according the second condition is
=(4)4×4!×12!×12!×12!×12!48!
So our answer is =(4)4×4!×12!×12!×12!×12!48!
Note: We used permutations to solve above questions. Note that in both cases, the number of ways to distribute the remaining 48 card to 4 groups is =12!×12!×12!×12!48! . We divided by 12!×12!×12!×12! because we have to arrange them in groups. If we were arranging 48 cards to 48 groups then we would have divided by 1!×1!×1!×1! which is eventually 48!.
