Classical Probability


The formula for the probability for an event \(E\), for a probability experiment with a finite number of outcomes, i.e. a finite sample space, \(S\)

\[P(E)=\frac{\text{number of outcomes in the event }E}{\text{number of outcomes in the sample space}}=\frac{n(E)}{n(S)}=\frac{|E|}{|S|}\]
