I hope that source is more readable now. f = Piecewise[{{2/355, Inequality[2, LessEqual, w[2], LessEqual, 8] && Inequality[4, LessEqual, w[2] + w[3], LessEqual, 12] && Inequality[5, LessEqual, w[1] + w[2], LessEqual, 10] && w[1] <= 0 && w[3] <= 0}}, 0] int1 = Integrate[f, {w[2], -Infinity, Infinity}] red1 = Reduce[Inequality[2, LessEqual, w[2], LessEqual, 8] && Inequality[4, LessEqual, w[2] + w[3], LessEqual, 12] && Inequality[5, LessEqual, w[1] + w[2], LessEqual, 10] && w[1] <= 0 && w[3] <= 0] int2 = Integrate[(2/355)*Boole[red1], {w[2], -Infinity, Infinity}] thanks a lot!
