You cannot remember your 5-digit bike-lock combination. What is the probability that you guess the combination correctly? (Enter your probability as a fraction.)

If the combination  can't start with  0

 

1 / [ 9 * 10^4 ]   =   1 / 90000

 

If  it can start with 0

 

1 / 10^5     =   1 / 100,000
