This are Spanish Lotto numbers from 1985 to 2006. We can see in this graphic the frequency of lottery numbers, from Loteria Primitiva and Bonoloto (these are two lottery games based in choosing 6 numbers among 49, 6/49) in Spain from 1988 to 2006. each color represents one number from 1 to 49. The lines point the frequency of appearance of every number from one year to the the following one." The center has a frequency of 4% & the outer ring of 20%. all numbers tend to group around a circle that would be in the value of 12,24% (6/49). That's the probability of any given number to appear in the winning combination of numbers. The peak on the outer line of 2006, for instance, is number 41 (green color) & has a value of 18%, which is the frequency of appearing as winner in that year.
