A computer manufacturer purchases motherboards from 3 producers
D, E, and F Suppose that the manufacturer purchases 50% of the
motherboards from D, 30% from E, and the rest from F. We know that
2% of the motherboards produced by D, 3% by E, and 5% by F are
defective (event D).
a) Calculate the probability that a motherboard is defective and
is purchased from D. Use formula and show your work.
