例題1: 若X ~ Bin(9,0.5)，求P(X=4)。
按 2ndF DEL (必要) RCL F1 ALGB 9 = 4 = 0.5 = (顯示答案為0.24609)
例題2: 若X ~ Bin(9,0.5)，求P(4≦X≦6)。
按 2ndF DEL (必要) RCL F1 ALGB 9 = 4 = 0.5 = (顯示P(X=4)的值) = (顯示P(X=4)+P(X=5)的值)
= (顯示P(X=4)+P(X=5)+P(X=6)的值，答案為0.65625)
例題3: 梯形法則，子區間數目為10，計算
按 2ndF DEL (必要) 2ndF ex 2ndF ALPHA X (變數X的函數方程) RCL F1
∫dx 0 = 1 = 10 = (顯示1.719713491)
所以=1.719713491
