S P(A) is the probability that event A happens It is a function that maps the event A onto the interval [0, 1]. P(A) is also called the probability measure of A Kolmogorov axioms Non-negativity: p(A) − λ)f (x2) where λ ∈ [0, 1] Jensen’s Inequality Let f (x) be a convex function defined on an interval I. If x1, x2, · · · , xN ∈ I and λ1, λ2, · · · , λN ≥ 0 with �N i=1 λi = 1 f ( N � i=1 λixi)

Jensen’s Inequality Theorem 1. Jensen’s Inequality Let f(x) be a convex function defined on an interval I. If x1, x2, · · · , xN ∈ I and λ1, λ2, · · · , λN ≥ 0 with �N i=1 λi = 1 f( N � i=1 λixi) ≤
