The Probability of an Event E Can Always Be Computed $$P ( E ) = \frac { \text { number of outcomes favorable to } \mathrm { E } } { \text { number of outcomes in the sample space } }$$

The probability of an event E can always be computed using the formula, $$P ( E ) = \frac { \text { number of outcomes favorable to } \mathrm { E } } { \text { number of outcomes in the sample space } }$$
