For the first digit you have 5 options, whichever you choose for the first digit, you have 4 options for the second digit, etc.; so the number of combinations is 5 x 4 x 3 x 2.

That makes a total of 3600 5-digit combinations.

How many area codes are there if first digit cannot be zero?

It depends on the other restrictions you place on possible area code numbers. Many countries have area codes of variable length. If you have a three-digit area code (as in North America, Turkey, or Russia) with no restrictions other than that the first digit cannot be 0, that leaves 900 possibilities. The actual restrictions on area codes in North America are that the first digit cannot be 0 or 1, the second digit cannot be 9, and the third digit cannot be the same as the second. That leaves only 648 possibilities, not including special codes like 800. (The 72 codes with the second and third digits the same are reserved for special purposes.)

The area code for a phone number consists of 3 digits How many possible area codes are there?

It depends on what restrictions you place on the three-digit numbers that are usable as telephone area codes. There are 1,000 three-digit numbers, if you include every combination from 000 through 999. In North America, though, 3-digit area codes have significant restrictions. The first digit cannot be 0 or 1 and the second digit cannot be 9. Area codes of the form N11 are not allowed due to conflicts with short codes for things like emergency services (911) and TDD relay (711). Other area codes with the second and third digits the same (such as 800, 888, 844, and 900) are reserved as "easily remembered" codes. That brings the total down to 648 regular area codes plus 64 special "easily remembered" codes.


How many 4 digit numbers have 6 as their second digit?

There are 9 digits that can be the first digit (1-9); for each of these there is 1 digit that can be the second digit (6); for each of these there are 10 digits that can be the third digit (0-9); for each of these there are 10 digits that can be the fourth digit (0-9). → number of numbers is 9 × 1 × 10 × 10 = 900 such numbers.
