(Counting outcomes)
Probability often requires counting outcomes. Drawing 2 cards from a 52-card deck has C(52,2) = 1326 possible hands.
If 13 cards are hearts, drawing 2 hearts has C(13,2) = 78 outcomes. Probability of 2 hearts = 78 / 1326 = 0.059.
Combinations count equally likely outcomes. This makes them the foundation for calculating probabilities in discrete events.
