Explanation of Solution
Given:
Shelly can enter the school through 4 different doors. Once inside, she can go to her locker using 4 different sets of stairs and then 3 different hallways.
Concept used:
A work of 3 stages can be completed in total number of ways ( TW ) given by
Calculations:
Shelly can enter the school through 4 different doors. Once inside, she can go to her locker using 4 different sets of stairs and then 3 different hallways.
The process of reaching the locker entering through one door is shown in figure here.
Once entered the school through she can choose 4 stairs and 3 hall ways.

Since, there are 4 doors, so total number of ways to get the locker is
Thus, total number of ways Shelly get to her locker is
Conclusion:
Total number of ways Shelly get to her locker is
