Question

How many ways are there to build a computer password consisting of 5 letters? Letters in a password may be repeated. There are 26 letters in the alphabet.

Answer 1

Answer:

3250

Step-by-step explanation:

T = p x a-1 x a

T = 5 x 25 x 26

= 3250

the password total = 5 x 25 (not 26) x 26 = 3250
