Thirty percent of the lp-42 seals are purchased from shall seals, 20 percent from huller sales and the remaining 50 percent from crawf components. the manufacturer has extensive histories on the three suppliers and knows that three percent of the lp-42 seals shall seals are defective, five percent of seals from huller sales are defective and four percent of the seals purchased from crawf components are defective.
