I have a bike lock. It has three columns of the digets 1-9 and zero. I have forgotten the combination.
Three numbers need to be imputed. What are the possible lock cominations, so that i can try to break the lock?

Hello Alejandra,

Think about your question this way: How many three digit numbers are there? The answer is all the numbers from 000 to 999. That's the same number as the possible combinations on your lock.
