From this we then evaluate probabilities. If doing this by hand, apply the poisson probability formula: P (x) = eâλ â λx x! 0.9750021048517795 Male Female Age Under 20 years old 20 years old level 30 years old level 40 years old level 50 years old level 60 years old level or over Occupation Elementary school/ Junior high-school student A normal distribution is a type of continuous probability distribution for a real-valued random variable. The NORM.S.DIST function can be used to determine the probability that a random variable that is standard normally distributed would be less than 0.5 This calculator will compute the cumulative distribution function (CDF) for the normal distribution (i.e., the area under the normal distribution from negative infinity to x), given the upper limit of integration x, the mean, and the standard deviation.
