TriangularDistribution

TriangularDistribution[{min, max}]
represents a symmetric triangular statistical distribution giving values between min and max.

TriangularDistribution[{min, max}, c]
represents a triangular distribution with a maximum at c.

The mean of a pair of uniformly distributed random variables follows a symmetric triangular distribution. »

TriangularDistribution allows min, max and c to be any real numbers such that min<c<max.

TriangularDistribution can be used with such functions as Mean, CDF and RandomReal. »
