# Question: Three parts are assembled in series so that their critical

Three parts are assembled in series so that their critical dimensions x1, x2, and x3 add. The dimensions of each part are normally distributed with the following parameters:

1 100,1 4, 2 75, 2 4, 3 75, 3 2 .

What is the probability that an assembly chosen at random will have a combined dimension in excess of 262?
