Question

A factory uses three production lines to manufacture cans of a certain type.  The accompanying table gives percentages of nonconforming cans, categorized by type of non-conformance for each of the three lines during a particular time period.  During this time period, line 1 produced 100 non-conforming cans, line 2 produced 100 such cans, and line 3 was responsible for 300 non-conforming cans.  A Quality Control person picks up a non-conforming can produced by one of the three lines.  What is the probability that the can was produced by Line 1?  (State your answer as a decimal accurate to three decimal places).

   Line 1   Line 2  Line 3 
Blemish   15%   12%   20%
Crack   50%   44%   40%
Pull-Tab Problem    21%   28%   24%
Surface Defect   10%    8%    15%
Other     4%    8%    1%
