The number of different six-character passwords can be made with 26 letters and 10 numerals is approximately:

a) 2.2 million
b) 2.2 billion
c) 2.2 trillion
d) 2.2 quadrillion

Answer 1

The number of different six-character passwords that can be made with 26 letters and 10 numerals is approximately 2.2 billion.

Step-by-step explanation:

To find the number of different six-character passwords that can be made with 26 letters and 10 numerals, we need to calculate the total number of combinations. Since each position can have 36 different options (26 letters + 10 numerals), we raise 36 to the power of 6 (as there are 6 positions in the password). This gives us a total of 36^6, which is equal to 2,176,782,336 possible passwords.
