The function of the triangular distribution of a random variable is defined by the formula:
The density of the triangular distribution of a random variable is found by the formula:
Mathematical expectation:
$M(x) = \frac{{a + b + c}}{3}$
Dispersions:
Density plot of a triangular distribution of a random variable in the range from -4 to 10

The triangular distribution is an approximate model and is used when there is no data available. The triangular distribution law is also used to construct complex distribution laws.
