Question

A password contains six digits, such as 174668. How many different passwords can be formed

Answer 1

Answer: The number of different passwords can be formed = 1,000,000

Explanation:

In general total digits = 10 [ from 0 to 9]

If a password contains 6 digits, then by fundamental principal of counting, the total number of different passwords =
`10*10 *10*10*10*10=10^6=1000000`

Hence, the number of different passwords can be formed = 1,000,000
