You can put this solution on YOUR website! in one deck of cards there are:
4 aces (1 for each suit)
4 kings (1 for each suit)
4 queens (1 for each suit)
4 jacks (1 for each suit)
36 cards from 2 to 10 (9 for each suit)
the suits are spades, clubs, hearts, diamonds.
the number of ways to get each one of these is:
4c2 for 2 aces from 4 aces = 6
4c1 for 1 king from 4 kings = 4
4c1 for 1 queen from 4 queens = 4
4c3 for 3 jacks from 4 jacks = 4
36c6 for 6 cards from 36 cards that are numbered from 2 to 10 = 1,947,792
the number of possible ways you can get 2 aces, 1 king, 1 queen, 3 jacks, 6 other cards is:
6 * 4 * 4 * 4 * 1,947,792 = 759,472,128
ncx equals the combination formula to get sets of x from n which is equal to n! / (x! * (n-x)!)
for example:
4c2 = 4! / 2! * 2! = (4*3*2*1) / (2*1*2*1) = 24 / 4 = 6
the assumption with the cards from 2 to 10 is that any combination of 6 of them can be part of your hand without any restrictions, i.e., you could have 4 sevens and 2 eights or you can have 2 sevens and 2 eights and 2 nines, oryou can have a straight flush, etc.

two aces;
4 aces Choose 2
That's 4C2 = 6 ways
one king;
4 kings Choose 1
That's 4C1 = 4 ways
one queen;
4 queens Choose 1
That's C(4,1) = 4 ways
three jacks;
4 jacks choose 3
That's C(4,3) = 4 ways
and the six other cards, ten or less
There are 9 ranks (2,3,4,5,6,7,8,9,10) of 4 suits each.
That makes 9*4=36 cards which are ten or less.
36 cards ten or less Choose 6
That's C(36,6) = 1947792
Answer: (4C2)(4C1)(4C1)(4C3)(36C6) = (6)(4)(4)(4)(1947792) = 747952128 ways.
