Answer 1

a) 2 Pairs can be formed as = 13* 4C2 * 12* 4C2 * 44C1 / 52C5 =0.09507803

Hence we can say that 13 possibilities of getting 2 cards from a 4of a kind denomination

Now we have 12 remaining possibilities of selection 2 cards from a 4of a kind denomination

and now for the erst of teh denomination we have 44 cards from which we have 1 card to be selected

why 44 because 52-4(of 1st pair)-4(of 2nd pair)=44

b)for four of a kind we can select = 13* 4C4 * 48C1 / 52C5 =0.000240096

i.e. 4 cards of the same denomination 4C4 but we have 13 possible categories

So it's is 13 * 4C4

and for the rest we have 48 cards from which 1 card to be selected hence 48C1

While total possible selection are 52C5
