Chapter 6, Problem 30RE

Inventories OHaganBooks.com currently operates three warehouses: one in Washington, one in California, and the new one in Texas. Exercises 25–30 are based on the following table, which shows the book inventories at each warehouse:

Sci Fi Horror Romance Other Total
Washington 10,000 12,000 12,000 30,000 64,000
California 8,000 12,000 6,000 16,000 42,000
Texas 15,000 15,000 20,000 44,000 94,000
Total 33,000 39,000 38,000 90,000 200,000

Take the first letter of each category to represent the corresponding set of books; for instance, S is the set of sci fi books in stock, W is the set of books in the Washington warehouse, and so on. In each exercise, describe the given set in words, and compute its cardinality.

( S ∩ W ) ∪ ( H ∩ C ′ )
