mean value of the information content of the events in a finite set of mutually exclusive and jointly exhaustive events, that is in mathematical notation H(X) = [...] p(xi)l(xi) = [...] p(xi)log 1/p(xi) where X = {x1 ... xn} is the set of events xi (i = 1 ... n), l(xi) are the information contents of the events xi, and p(xi), the probabilities of the occurrences of these events, subject to [...] p(xi) = 1 1, record 1, English, - entropy

Example: Let X = {a,b,c} be a set of three events and let p(a) = 0,5, p(b) = 0,25 and p(c) = 0,25 be the probabilities of their occurrences. The entropy of this set is H(X) = p(a) l(a) + p(b) l(b) + p(c) l(c) = 1,5 Sh 1, record 1, English, - entropy
