Question

You are trying to hack into your mom's computer. You know your password is 4 letters and then a number but you can not remember what it is so you start guessing. How many possible passwords can you guess?
O 120
O 3,588,000
O 24
O 4,569,760

Answer 1

The amount of passwords you can guess are 4,569,760. 
 How this is found is by multiplying the amount of numbers in the alphabet by itself 4 times, then multiplying by the amount of 1 digit numbers there are, so multiply by 10, it is ten because you can have the number as 1 2 3 4 5 6 7 8 9 or 0, and then the number you get is your answer. Hope this helped! ^_^
