1. 정규분포 normCdf(lowBound,upBound[,μ[,σ]]) ⇒ number if lowBound and upBound are numbers, list if lowBound and upBound are lists Computes the normal distribution probability between lowBound and upBound for the specified μ (default=0) and σ (default=1). For P(X ≤ upBound), set lowBound = -9E999. 문제 출처 : http://math7.tistory.com/49 1. 평균 800, 표준편차 40 정규분포 x≤750 일 확률? normCdf(−∞,750,800,40) = normCdf(−∞,−1.25,0,1) = normCdf(−∞,−1.25) = 0.10564983896266 2. 평균 11, 분산 16 정규분...
