Document Summary
P (a) = lim n relative frequency = lim n frequency n. Frequency is the number of times that event a occurred. n is number of times that experiment repeat. 1: calculating probability by using sample space: One of the method for computing probability is using simple events and. P (a) = n(a) n n : number of simple events in sample space. n(a) : number of simple events contained in a. There is some rule for counting n and n(a) which are needed for calculate p (a). The mn rule: if an experiment is performed in two stages, with m ways to accomplish the. Rst stage and n ways to accomplish the second stage, then there are mn ways to accomplish. If experiment has k stages, then n = n1 n2 nk such that n1 is number of ways for. Permutation: there are n distinct objects and want to choose k objects in order, then there are.
