translation: "we can see in this graphic the frequency of lottery numbers, from Loteria Primitiva and Bonoloto (these are 2 lottery games based in choosing 6 numbers among 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."
the chart comes from Onlae (Loterias y apuestas del estado, the public company that runs lotto games in Spain).
