Definition 6: X is a . Continuous Random Variable. if there exists a non-negative function f defined for all real numbers, having the following property: For every set B of real numbers, P[XB] = . f. is the . Probability Density Function of X. In other words, the probability that X is in the set B can be found by integrating f over the set B.

cumulative probability distribution function. gives the probability that the value of the random variable is less than or equal to x. CDF’s are usually denoted by a capital letter, such as P(x) or F(x). For continuous variables, probability density functions (pdf) and . cumulative density functions (cdf) are …

Here the mass is the probability. Cumulative Distribution Functions. The cdf F of a continuous random variable has the same definition as that for a discrete random variable. That is, . In practice this means that F is essentially a particular antiderivative of the pdf since . Thus at the points where f …

The probability mass function provides us with the ability to compute the probability of the load being within a range according to: We may use the probability mass function to obtain the cumulative distribution function (CDF) according to: From Fig. 8, we obtain: Plotting these values vs. the load results in the CDF of Fig. 9.
