A system consists of four components connected as shown in the following diagram:
|
Lot
|
Conforming
|
Nonconforming

a. If the wafer is from Lot A, what is the probability that it is conforming?
b. If the wafer is conforming, what is the probability that it is from Lot A?
c. If the wafer is conforming, what is the probability that it is not from Lot C?
d. If the wafer is not from Lot C, what is the proba- bility that it is conforming?
