Given :
A credit card company requires that its customers choose a 3 digit.
Each digit should be chosen from 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9.
So there are 10 possibilities for each digit.
To Find :
How many different three digit codes are there.
Solution :
We know, possibility of choosing each digit is 10.
So, total number of three digit codes are :
[tex]T=10\times 10\times 10\\\\T=1000[/tex]
Therefore, their are 1000 different three digit codes.
Hence, this is the required solution.
