Say that COOP Ale Works, an Oklahoma brewery, uses three production lines to manufacture
beer cans. The table below gives percentages of nonconforming cans, categorized by the type
of nonconformity, for each of the three lines during a particular year. During this period, line 1
produced 500 nonconforming cans, line 2 produced 400 such cans, and line 3 was responsible
for 600 nonconforming cans. Suppose that one of these 1500 cans was selected at random.
