Answer:
120 different ways
Explanation:
For the first shopping mall being visited, the candidate has 5 options
Then, for the second mall being visited, there is only 4 options, as one mall was already visited.
Following this logic, there is 3 options for the third mall, 2 options for the fourth mall and 1 option for the last mall.
So the total number of ways that the visits can be scheduled is the product of all these options:
5*4*3*2*1 = 120 different ways
