Question 666375: until 1995 area codes could not have a first digit of 0 or 1 and the second digit had to be a 0 or a 1 the third digit could be anything how many possible area codes were there? Answer by swincher4391(1107) (Show Source):
You can put this solution on YOUR website! First digit there are 8 possibilities (2-9)
Second digit there are 2 possibilities (0,1)
Third digit there are 10 possibilities (0-9)
Fundamental Counting Principle tells us that there are 8*2*10 possible area codes. Hence, there are 160 possible area codes.
