\[\text{Probability}=\dfrac{\text{number of ways to succeed}}{\text{total number of possible outcomes}}\]

This is helpful when finding probabilities of drawing a colored marble out of a bag or a card from a deck. For instance, what is the probability that you draw a heart out of a standard deck of cards? Since there are 13 total hearts and 52 total cards,

\[\text{Probability}=\dfrac{13}{52}=0.25=25\%\]
