概率论的中心极限定理问题..
6．(10 points) Suppose that a random sample is to be taken from a Bernoulli distribution
with p = 0.2.Use the central limit theorem to find approximately the size of a random
sample that must be taken in order that
Pr(| X − p |≤ 0.1) ≥ 0.95.

let X be the frequency,Ybe the nummber of occurence=nX
-0.1
再问：
再答： 我最後算反了，应该是 1.96^2*16
这个答案步骤和我的一模一样没什麼可解释的了
