When Ted goes through the broken racquets downstairs, he should classify each racquet by the year it was produced and the company that supplied the material. This would give him a contingency table containing all the information about the broken racquets.

Then, using the relative frequency approach, Ted could find the probability that a broken racquet was produced in each of the past 6 years that the broken racquets have been saved. This would give Ted an idea as to whether there really have been more complaints since the company added a third supplier.

He could also take the racquets that were produced in the last year and a half, and find the probability that a broken racquet was made from materials received from each of the three suppliers. Then he could compare these three values to see if there really are more broken racquets that are made from the materials obtained from the third supplier. If so, Ted should strongly consider dropping the third supplier and just using the original two suppliers.
