I m also unable to interpret the que

so what we have to do is place given digits to maximum four slots (because a number smaller than \(10^4\) has 4 digits) and find how many combinations we can make. When doing that we should neglect the occasion where 0 comes as the left most digit also

Does this question means how many \(4\) digit numbers can be made with \(\{0,1,2,3,5\}\) no repetition allowed

  • BAdhi
not only 4 digits it could be 3,2 or 1 also since all of them are less than 10^4
