Question

How many bicycle license tags can you make with four numeral spaces? Use 10 digits and no blank spaces.



400

1,000

10,000

Answer 1

10,000 because it would be 0000 - 9999.

Answer 2

so the license tags should include 4 numbers right ?

Answer 3

ok so
the first number can take one of 10 numbers
the second --> one of 10 numbers
the third --> one of 10 numbers
the fourth --> one of 10 numbers

so at the end 10*10*10*10=10.000 numbers

Answer 4

So what i said

Answer 5

lol yall are both right, thanks!!

Answer 6

yes @IsaiahCC100 we can see it like this way it's the number of "numbers" from 0000 to 9999 ---> 9999-0000+1=10.000
and the solution I gave is using analytic combinatorics :)

Answer 7
