利用大数定律和中心极限定理求解极限

Using Law of Large Number and Central Limit Theorem to Work out Limit

引进随机变量,用概率中的大数定律,解决一类特别的n重积分的极限问题,还利用中心极限定理,求解结论中含有正态分布模式的极限问题。

Ushering in random variables, the essay uses the law of large number of probability to solve a type of limit issue of n-lay integration. It also makes use of central limit theorem to solve extreme limits with normal distribution mode in the conclusion.
