Four numbers for my set 0 to 9 including 0 9 are used to create a personal identification number once a numbers use it cannot be reused how many possible outcomes begin with a 0

504

Step-by-step explanation:

Given : The number of digits used to make the personal identification number  =10

The total digits in the personal identification number =4

If repetition of digits is not allowed then the number of possible outcomes is given by permutations .

The number of possible outcomes begin with a 0 is given by [ first place is fixed for 0, so we take 1 for it then apply permutation on the rest of 9 digits taking 3 at a time]:-

Hence, the possible number of outcomes =504
