CCSS IP Math III 1.6.1 Example 1

Suppose the U.S. State Department distributes 140,000 visas for people to come to work in the United States each year. The visas are distributed among five preference categories (E1–E5), with E1 being the highest-priority category, then E2, and so on. The first three categories each receive 28.6% of the available visas, and the fourth receives 7.1%. Is the process fair for all applicants?
