The number of different passwords that are possible is:d. 6,760,000.

Based on the information given let the four numbers be:

Numbers=10,10,10,10

Since alphabet has 26 letters let the 2 letters will be:

Letters=26,26

Now let calculate the different passwords that are possible

Different passwords=10×10×10×10×26×26

Different passwords=6,760,000

Inconclusion the number of different passwords that are possible is:d. 6,760,000.

Total number of characters in the computer password =7.

Number of letters used = 4 letters.

Total numbers used = 3 numbers.

There are 26 English alphabets.

For first character number of options = 26.

For second character number of options = 26.

For third character number of options = 26.

For fourth character number of options = 26.

For fifth character number of options(number from 0 to 9) = 10.

For sixth character number of options = 10.

For seventh character number of options = 10.

Therefore, total number of different possible passwords = 26× 26× 26× 26× 10×10×10= 456976000.Therefore, correct option is 3rd option c. 456,976,000.

A, B, E

Step-by-step explanation:

Permutations are involved when order matters, as in lane assignment, passwords, and seating charts.

When the end result is a "group of 10 students", "3 employees", or "4 cashiers", clearly order does not matter. One student, employee, or cashier is as good as another in these cases.
