I get in when there is 1 card - how do I figure it out when there is 2? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Two cards are drawn from a standard deck of 52 cards.
What is the probability of
1) P(2 spades) = 13C2/52C2 = 78/1326 = 0.0588235
----------------------------------------------------------
2) P(2 spades or 2 red cards) 0.0588.. + 26C2/52C2 = 0.3039...
----------------------------------------------------------
3) P(2 red cards or 2 jacks) = [26C2 + 4C2]/52C2
-----------------------------------------------------------
4) P2 spades or 2 face cards) = [13C2 + 16C2]/52C2
