A salesman in a
department store receives household appliances from three
suppliers:
I, II, and III. From previous experience, the salesman knows that
2%, 1%, and 3% of the
appliances from suppliers I, II, and III, respectively, are
defective. The salesman sells 35%
of the appliances from supplier I, 25% from supplier II, and 40%
from supplier III. If an
appliance randomly selected is defective, find the probability that
it comes from supplier
III.
