Q3. An automobile plant contracted to buy shock absorbers from two suppliers X and Y. X supplies 60% and Y supplies 40% of the shock absorbers. All shock absorbers are subjected to a quality test. The ones that pass the quality test are considered reliable Of X's shock absorbers, 96% are reliable. Of Y's shock absorbers, 72% are reliable. The probability that a randomly chosen shock absorber, which is found to be reliable, is made by Y is
Answer : Option B
Explaination / Solution:

                  x           y 
Supply     60%     40% 
Reliable   96%     72% 
Overall     0.576   0.288
P(x) = 0.288/(0.576 + 0.288) = 0.334
