WebContinuous Distribution Calculator. For a continuous probability distribution, probability is calculated by taking the area under the graph of the probability density function, written f (x). For the uniform probability distribution, the probability density function is given by f (x)= { 1 b − a for a ≤ x ≤ b 0 elsewhere. WebThe expected value formula calculates the average long-run value of the available random variables. Then, according to the formula, the probability of all the random values is multiplied by the respective probable random value. Finally, all the results add together to derive the expected value. felicity of whole family
