    {number_of_remaning_cards_with same_suit_left} / {total_cards_left}. If you pick Hearts, than it's 13-1, and 52-1...

    In a 52 card deck there are: - 4 suits - 13 cards per suit.

    We want to find: P(2 cards of same suit wo/ replacement)

    Favorable outcomes: 13C2 = 13!/2!(13-2)!

    Total possibilities: 52C2 = 52!/2!(52-2)!

    Since there are 4 suits: P(X) = 4 * 13C2/52C2

    from itertools import combinations
lst = list(13*'c' + 13*'d' + 13*'h' + 13*'s')
comb = list(combinations(lst,2))
x = [i for i in comb if i[0]==i[1]]
print(len(x) / len(comb))
