摘要
本文利用建立概率模型,证明几个重要的恒等式。有些恒等式用常用的分析方法证明是很不易的,但建立了概率模型后,通过求概率或求数学期望,很方便地把恒等式证明出来。
The article mainly discusses how to prove important inequality through building probability model.The proof of some identity is difficult to rose common methods of analysis and becomesvery convenient to explore probability or mathematical expectation after building the probability model.
