Probability and distribution pdf article is about probability distributions. This article has multiple issues.

In contrast, when a random variable takes values from a continuum then typically, any individual outcome has probability zero and only events that include infinitely many outcomes, such as intervals, can have positive probability.

500 g is zero, because the probability of measuring exactly 500 g tends to zero as the accuracy of our measuring instruments increases. Continuous probability distributions can be described in several ways. Gaussian or “bell curve”, the most important continuous random distribution. As notated on the figure, the probabilities of intervals of values correspond to the area under the curve. As probability theory is used in quite diverse applications, terminology is not uniform and sometimes confusing. It may for instance refer to a table that displays the probabilities of various outcomes in a finite population or to the probability density of an uncountably infinite population.
