Textbook Question
Chapter 3.1, Problem 19MS
Dining hall blues. One day in Ralph P. Uke Dining Hall, the students in line discovered that no more forks were available (neither clean nor dirty). While there was much jubilation in the line, what can you conclude about the set of all students in the dining hall and the set of all forks? (Assume that every student with a fork has only one.) Do we know how many forks there are? How many students? Discuss who the idea of one-to-one correspondence is relevant in addressing these questions.
