Powerball Numbers

Simple analysis of Powerball lottery stats with Enumerable

Lottery info is at http://www.powerball.com

Retrieves lottery drawing results from "today" back to the beginning of the Powerball epoch (1 Nov 1997) and lists the 5 most-often-drawn numbers and most-often-drawn Powerball, in addition to listing how many times each number and each Powerball has been drawn.

Note the numbers included in the game have expanded over time, so numbers in the 50s appear disproportionately few times.

Requires the hpricot gem. Runs in 1.9.3; unsure of earlier versions.
