There is a local radio station here that does a one dollar bill game. The game revolves around the fact that the stations call numbers (973) are in the bills serial number in order.
Given that... how many bills would there be with 973 anywhere in the serial number?
I currently have 5 in my possesion even though I don't listen to that radio station ><

Okay, there are 8 digits in a serial number. Do the 973 have to be sequentially in order.
Example: 84957230 (would that count, since there are other numbers between them).
Example: 84973520 (in this one they are sequential).

If 973 was the last three digits, then you could have:
00000973
00001973
00002973
So, that is 5 digits that go from 0 to 99,999 - so that would be 100,000 possible combinations.
Or you could have:
00009730
00009731
00009732, same thing 100,000 combinations. So, now we have 200,000 combinations.
Then:
00097300
00097301........now we have 300,000 combinations.
00973000.........400,000
09730000.........500,000
97300000.........600,000 combinations.
So, out of the 99,999,999 to 0 = 100,000,000 total combinations 600,000 could have a 973 in sequential order.
Odds of finding one 600,000/100,000,000 = 600/100,000 = 6 / 1,000. So, if you had 1,000 bills, 6 should work.

In a 30 mile radius, there should be 447 bills with the right serial number.

In a 10 mile radius, there should be 50 bills.

In a 1 mile radius, there would be a 50:50 chance of finding one bill with that number.
