On a bike lock there are three tumblers where the digits 0, 1, 2, ...., 9 appear on each tumbler. A lock is going to be a three
digit code (where numbers can be repeated). Find the number of possible codes for the lock.
1 answer:
Answer: 1000
Step-by-step explanation:
The number of combinations is equal to the product of the number of options for each tumbler.
Each tumbler has 10 possible numbers, and we have 3 tumblers, then the number of combinations is:
C = 10*10*10 = 10^3 = 1000
We have 1000 possible codes for the lock.
