Question

BRAINLIEST!!!
A website requires users to set up an account that is password protected. If the password
format is four letters (A-Z) followed by a single digit number (0-9), and letters can be repeated, how
many different passwords are possible?

Answer 1

Answer:

Number of dispositions of 4 letters without repetitions of the alphabet (26 letters): 26*25*24*23=358800. 58 different password

Step-by-step explanation:

Answer 2

Answer:

58 different password combos!

Explain:

there are 26 alphabetical letters (A through Z)

and 9 numbers

26 x 9 = 234

but were only using 4 random letters so we divide:

234 ÷ 4 = 58.5 rounded = 58 because the password wouldnt be complete otherwise!

Hope you have a wonderful day! :)
