A lock code has 4 digits in a specific order, the digits are between 0-9 (so 10 total numbers to pick from). 1. How many different lock codes can there be if the digits can be repeated? For example, a code can be 0000. 2. Explain how you got your answer. 3. How many different lock codes are there if each digit may only be used once? For example, a code can not be 0103 because 0 cannot be used more than once. Explain your thinking. 4. Explain how you got your answer.
