Two suppliers each supplied 2000 parts that were evaluated for conformance to specifications. One part type was more complex than the other. The proportion of nonconforming parts of each type are shown in the table.

One part is selected at random from each supplier. For each supplier, separately calculate the following probabilities:

(a) What is the probability a part conforms to specifications?

(b) What is the probability a part conforms to specifications given it is a complex assembly?

(c) What is the probability a part conforms to specifications given it is a simple component?

(d) Compare your answers for each supplier in part (a) to those in parts (b) and (c) and explain any unusual results.
