概略二項式機率（Normal Approximation of Binomial Probability）

GNU R:

# Normal Approx of Binomial Probability BinomialMean <- function(sampleSize, mySuccessProbability) { myMean <- sampleSize * mySuccessProbability myMean } BinomialStdDeviation <- function(sampleSize, mySuccessProbability) { myStdDeviation <- sqrt(sampleSize * mySuccessProbability * (1 - mySuccessProbability)) myStdDeviation } BinomialStdDeviation2 <- function(myMean, mySuccessProbability) { myStdDeviation <- sqrt(myMean * (1 - mySuccessProbability)) myStdDeviation }

應用：

• 公聽會上政策支持度機率計算

• 閱讀保險契約機率計算
