WebIn case of BinomialCDF, I tried solving this problem manually. Because P (X<=4), therefore, I calculated P (X=1)+ P (X=2)+P (X=3)+P (X=4) = 0.89537 which does not match with your result. Then I calculated P (X=1)+ P (X=2)+P (X=3)+P (X=4)+P (X=5) = 0.94197 which also does not match with your result. Am I doing it wrong?
