A probability mass function (PMF), sometimes referred to as a frequency function, is a function that associates probabilities with discrete random variables. You already learned about this in the ...

In this lesson, you'll look at a way to represent discrete distributions - the probability mass function (PMF), which maps from each value to its probability. A probability mass function (PMF), ...

Unlike for probability mass functions, the probability density function cannot be interpreted directly as a probability. Instead, if we visualize the graph of a pdf as a surface, then we can compute ...

Suppose that the probability mass function (PMF) for the discrete random variable X is: f(x) = x/9 x=2,3,4 and zero otherwise. Double click on the top of Column 1 to change the name to x (or right ...

We show that any joint probability mass function (PMF) can be expressed as a product of parity check factors and factors of degree one with the help of some auxiliary variables, if the alphabet size ...

In this letter, closed-form non-recursive expressions for the probability mass function (pmf) of the access delay are addressed. As the exact non-recursive expression for the pmf of the access delay ...
