Answer:
360
Explanation:
Given that Amir wants to create a 4-digit password for his phone.
He wants to choose 4 different numbers between 1 and 5 inclusive.
The total number of 4-digit passwords that Amir can create will be achieved by using permutation
6P4 = 6!/ ( 6 - 4)!
6P4 = (6 × 5 × 4 × 3 × 2!)/2!
6P4 = 6×5×4×3 = 360
Therefore, the total number of 4-digit passwords that Amir can create is 360 different passwords.
