Answer:

100,000

Step-by-step explanation:

From 0 to 99,999.

99,999 + 1 = 100,000

Also, there are 5 digits, and each digit can be one of ten.

10 × 10 × 10 × 10 × 10 = 100,000

Answer:

90 000 possibilities

Step-by-step explanation:

I will assume that numbers beginning with  0  are not valid  

  AND assume you can repeat the numbers

9 choices for first digit    ( because you can't use ' 0 ' )

10 choices for second

10 choices for third

10 choices for fourth

10 choices for last

9 x 10 x 10 x 10 x 10 = 90 000
