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

Assuming there are 10 digits possible for each spot in the combo

 

10 * 9 * 8 * 7 * 6 = 30 240 possible combinations     you have a   1 / 30,240   chance of guessing on your first try
