For audio work, 20 ms is a
typical choice for a frequency-independent frame length.
A discrete random variable can take only a finite number of distinct values such as 0, 1, 2, 3, 4, … and so on. Other ranges of values would have half the probabilities of the last example.
In examples such as these, the sample space is often suppressed, since it is mathematically hard to describe, and the possible values of the random variables are then treated as a sample space.

The probability distribution “forgets” about the particular probability space used to define
X
{\displaystyle X}
and only records the probabilities of various values of
X
{\displaystyle X}
.
Put your understanding of this concept to test by answering a few MCQs. You are familiar with the concept of functions. Recall,

The most obvious representation for the two-dice case is to take the set of pairs of numbers n1 and n2 from {1, 2, 3, 4, 5, 6} (representing the numbers on the two dice) as the sample space. 8 It can be realized as a mixture of a discrete random variable and a continuous random variable; in which case the CDF will be the weighted average of the CDFs of the component variables. For example:
If a random variable
X
sites R
{\displaystyle X\colon \Omega \to \mathbb {R} }
defined on the probability space
(
,
F
,
P
)
{\displaystyle (\Omega ,{\mathcal {F}},\operatorname {P} )}
is given, we can ask questions like “How likely is it that the value of
X
{\displaystyle X}
is equal to 2?”. .
