Question 1068536: A bicycle factory runs two assembly lines, A and B. 95% of line A's products pass inspection and 92% of line B's products pass inspection. 60% of the; factory's bikes come off assembly line B and the rest come off line A. Find the probability that one of the factory's bikes did not pass inspection and came off assembly line Upper AA. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Look at 1000 bikes, 400 from A, 600 from B
========Pass=======Fail=======Total
A----------380-----------20----------400
B----------552-----------48----------600
Total------932-----------68----------1000
Did not pass inspection was 68 and 20 came from A.
probability is 20/68 or 5/17=0.29
