What is the mnimum number of ways of choosing 4 cards from a pack of 52 playing cards? in how many of these:
1) are 4 card of the same suit?
2)do 4 cards belong to 4 different suits?
[I found the answer to 1) as 13C4+13C4+ 13C4+ 13C4. but when I don't understand how to solve question number 2. According to solutions it is given as 13C1 x 13C1 x 13C1 x 13C1= 13^4.
I understand how we got 13C1 but I don't understand why multiplication was used and not division]
