At a factory, 60 % of the widgets produced are type A and 40 % are type B. A type A widget is defective with probability 0.02, while a type B widget is defective with probability 0.05. A widget is chosen at random and is found to be non‑defective. (a) What is the probability that the selected widget is of type A? (b) If the factory produces 10 000 widgets, what is the expected number of non‑defective type B widgets?

Answer Options

A. Probability = 140\/242 (≈0.579); Expected non‑defective type B = 3800
B. Probability = 147\/242 (≈0.607); Expected non‑defective type B = 3500
C. Probability = 147\/242 (≈0.620); Expected non‑defective type B = 3800
Correct Answer D. Probability = 147/242 (≈0.607); Expected non‑defective type B = 3800
Correct Answer
D
Correct Option:
Probability = 147/242 (≈0.607); Expected non‑defective type B = 3800
