Question 3
On Sunday, Bob wants to play games and borrows his mother’s computer. However, her computer is password-protected. The password consists of his mother’s name, Emily, with exactly one capital letter, and her age (a two-digit number), placed before or after her name. Of course, Bob knows his mother’s name and age, but he still has to make some attempts to find the correct password.
What is the minimum number of attempts Bob needs to guarantee that he can unlock his mother’s computer?
