In how many ways can a hand of 4 spades be chosen from an ordinary deck of cards

Okay, This question asks how many ways a hand of six red cards could be chosen from a deck. So we know that there are 52 cards in a deck equally split between the two colors, black and red. And if we do that, that gives us 26 cards for color. So that means that we have 26 red cards in a standard deck, but we want a hand of six of them. So how many ways can we do that? Well, that's just 26 to 6, because the order doesn't matter. We just care about the subset. So 26 to 6, which is equal to 26 factorial divided by six factorial times 20 minus six, which is 20 that factorial, and this works out to be 230,000 230.
