【Abstract】 This paper studies the use of three probability properties in the proof of algebraic inequalities, including strong additivity of probability, nonnegativity of variance and linear property of expectation. We expound on how to construct random events and random variables according to the characteristics of the inequalities. Several examples with the detailed proofs are provided to show our approaches.更多还原
