TruncatedDistribution
TruncatedDistribution[{xmin, xmax}, dist] represents the distribution obtained by truncating the values of dist to lie between xmin and xmax.
TruncatedDistribution[{{xmin, xmax}, {ymin, ymax}, ...}, dist]represents the distribution obtained by truncating the values of the multivariate distribution dist to lie between xmin and xmax, ymin and ymax, etc.
Examples
