first make sure we have atleast one card from each suit
so number of ways getting 4 cards, one of each suits = 13^4
now we are left with 48 cards we need to draw 2 more, with no restrictions, numebr of ways = 48C2 = 48*47/2 = 24*47

total number of ways = (13^4)*24*47 ... Not an option :? .....

could you check the question...

I agree with durgesh79..

On second thoughts, is the answer (A) ?

4 cards from 4 suits = 13^4

Now the 5th card can be drawn in 48 ways and the 6th one in 47 ways

So the number of ways = 13^4 * 48 * 47
