Normal Probability Pdf Normal Distribution Probability Theory 2 probability distribution function: f(x) = pr(x x) what is the probability that a random variable x takes a value equal to or less than x? area under the density curve non decreasing kosuke imai (princeton university) probability pol 345 lectures 15 26. 7. normal (gaussian) distribution. normal distribution has two parameters, mean µ and variance σ2, f(x) = 1 √ 2πσ2 exp − (x−µ)2 2σ2 if µ = 0 and σ2 = 1, then it is called the standard normal distribution. we now consider the “truncation” of a probability distribution where some values cannot be.
