The Probability density function formula is given as, P ( a < X < b) = ∫ a b f ( x) dx Or P ( a ≤ X ≤ b) = ∫ a b f ( x) dx This is because, when X is continuous, we can ignore the endpoints of intervals while finding probabilities of continuous random variables. That means, for any constants a and b, See more

For example, the normal distribution is parametrized in terms of the mean and the variance, denoted by and respectively, giving the family of densities Since the parameters are constants, reparametrizing a density in terms of different parameters t…

Normal Distribution Formula. For a random variable x, with mean “μ” and standard deviation “σ”, the probability density function for the normal distribution is given by: Normal Distribution Formula: f(x) = 1 √2πσ2 e −(x−μ)2 2σ2 f ( x) = 1 2 π σ 2 e − ( x − μ) 2 2 σ 2. Where. μ = Mean. σ = Standard deviation.
