Need some guidance on how to solve such a problem. A company has 3 assembly lines(A,B,C). 5% of A's items needs rework, 8% of B's and 10% of C's. Supposing that 50% of all components are made on A, 30% on B and 20% on C. Question is, if a part is randomly selected what is the chance it came from line A? B? C?
So, each line produces the following percents of faulty parts.
So would the answers be those exact percentages as well?
Let me know if im on the right track here possibly?
