The scientific study of probability is a modern development of mathematics. Gambling shows that there has been an interest in quantifying the ideas of probability for millennia, but exact mathematical descriptions arose much later. There are reasons for the slow development of the mathematics of probability. Whereas games of chance provided the impetus for the mathematical study of probability, fundamental issues are still obscured by the superstitions of gamblers. WitrynaIt is also known as Gaussian distribution and it refers to the equation or graph which are bell-shaped. The formula for normal probability distribution is as stated: P ( x) = 1 2 π σ 2 e − ( x − μ) 2 / 2 σ 2. Where, μ = Mean. σ = Standard Distribution. x = Normal random variable. Note: If mean (μ) = 0 and standard deviation (σ) = 1 ...
