Cum distribution find density

WebIn statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.The general form of its probability density function is = ()The parameter is the mean or expectation of the distribution (and also its median and mode), while the parameter is its standard deviation.The variance of … WebCumulative Distribution Function Formula The CDF defined for a discrete random variable and is given as F x (x) = P (X ≤ x) Where X is the probability that takes a value less than or equal to x and that lies in the semi-closed interval (a,b], where a < b. Therefore the probability within the interval is written as P (a < X ≤ b) = F x (b) – F x (a)
