There are 26 red cards and 52 cards.
"26 choose 5" over "52 choose 5"
That's the probability of getting 5 red cards.
The same for getting 5 black cards, so

Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website! assume you are playing 5 card draw poker.... what is the probability of getting all 5 cards the same color
---------------------------------
# of ways to pick a color: 2
# of ways to pick 5 cards of that color: 26C5
-----------------------------------------------------
# of ways of picking 5 cards from the deck of 52: 52C5
=========================================================
P(5 cards same color) = [2*26C5]/52C5 = 131560/2598960 = 0.0506
