數(shù)學(xué)期望的應(yīng)用
摘要
數(shù)學(xué)期望是隨機(jī)變量的重要數(shù)學(xué)特征之1，本文通不過(guò)等式的證明、效益與利潤(rùn)和疾病普查等1些例子，闡述數(shù)學(xué)期望在數(shù)學(xué)其他分支和實(shí)際問(wèn)題的廣泛應(yīng)用。
關(guān)鍵詞：隨機(jī)變量；數(shù)學(xué)期望；數(shù)學(xué)期望的應(yīng)用
Applications of mathematical expectation
Abstract
Mathematical expectation is one of the important character of randon variable.the thesis will expound the application of the mathematical expectation in other embranchments of mathematical and real prombers,the prooves by some cases,such as of inequalities,profit and the investigation of illness,etc.
Keywords: Randon variable; Mathematical expectation; Applications of mathematical expectation
