How do you make a tree diagram for this problem
A library has five copies of a certain textbook on reserve of which two
copies (1 and 2) are first printings and the other three (3,4,5) are
second printings. a student examines these books in random order,
stopping only when a second printing has been selected. how do you make a
tree diagram for this problem?
