Using US Lotteries, Thanks BlackDave for the heads up.

I used 

Virginia - Cash 5 Triads of Numbers Analysis, Pairs Analysis & Combination Search

And came up with 7 lines all 34 numbers used...#12 used twice...pairs not coming up within last 100 draws wasn't used.

I then looked up each line to see how many times it has hit.

05-13-17-23-32 (127 3/5)
06-08-11-22-28 (4 4/5 & 105 3/5)
07-16-19-24-30 (4 4/5 & 98 3/5)
