In a fuse factory, machines A, B, and C
manufacture 25%, 40%, and 35%, respectively, of the total fuses. Of the
outputs for each machine, A produces 5% defectives, B
produces 2% defectives, and C produces 3% defectives. A fuse is
drawn at random.
Given that a fuse is defective, what is the probability it came from
a.0.7742, b. 0.3387, c. 0.4032, d, 0.2581, e. 0.3326
