Question: how many combinatoin possibility are there on a three combo lock? it is 4 my math homework

Answer: If there are three combinations and each can go from 0 to 9, there are ten possibilities. So you have 10 choices for the first number. For each of these, you have 10 choices for the second number, so there are 10*10=100 choices. For each of these, there are 10 separate choices for the third number, so there are 100*10=1000 choices.
