I feel someone else has done this, but what the heck I should do this here.

For 2 - 99, I count:

1) one even prime number ending in 2, that's 02

2) five prime numbers ending in one (six if you count 01)

3) seven prime numbers ending in three

4) one prime number ending in five (05)

5) six prime numbers ending in seven

6) five prime numbers ending in nine

For 100 - 199:

1) There are five prime numbers ending in one

2) There are five prime numbers ending in three

3) There are six prime numbers ending in seven

4) There are five prime numbers ending in nine

For 200 - 299:

1) There are five prime numbers ending in one

2) There are five prime numbers ending in three

3) There are three prime numbers ending in seven

4) There are three prime numbers ending in nine

and so on.

Of course as you get into higher ranges, you could lengthen them to get meaningful results. So now you have a better idea as to what prime numbers are all about.
