`The probability and odds can be taken into a mathematical perspective: The probability of winning the jackpot (through October 27, 2017) was 1:(75C5) x (15); that is: 75 ways for the first white ball times 74 ways for the second times 73 for the third times 72 for the fourth times 71 for the last white ball divided by 5 x 4 x 3 x 2 x 1, or 5!, and this number is then multiplied by 15 (15 possible numbers for the "Megaball"). Therefore, (75 x 74 x 73 x 72 x 71)/ (5 x 4 x 3 x 2 x 1) x 15 = 258,890,850, which means any combination of five white balls plus the Megaball has a 1:258,890,850 chance of winning the jackpot. Similarly, the odds for second prize are 1:(75C5) x (15/14) = 1: 18,492,204 chance of winning. The overall probability of winning any prize was 1 in 14.7. If there are no jackpot winners for a specific drawing, the jackpot will keep increasing, however, the odds will still remain the same.`

_{Lottery winners can choose to receive the money in either an annuity — annual allotments over 30 years — or to get it all at once in a single payment for a smaller amount. For example, the lump sum on the $502 million jackpot would be $301 million, according to lottery site USAMega.com. If a single winner takes the single payment, the federal tax withholding would be over $75 million. Then, there are state taxes too. }

*Based on statistical projections, the average jackpot win increased from $95 million to $141 million. Over 3.5 million additional prizes were expected to be won yearly due to the change in probability. The starting jackpot increased to $20 million, with minimum rollovers of $5 million. The jackpot contribution increased from 30.3% to 32.5% of total sales. The Power Play option was modified; second prize, usually $200,000, was given an automatic 5x multiplier, making the 5+0 prize $1 million cash. The bonus second prize if the jackpot exceeded its previous record by $25 million, triggered only twice, was eliminated with the 2012 format change.*

• Even the one-time cash option, about $308 million, won't go entirely in your pocket. It is subject to federal, state and local taxes, these days a little less than half taken out — state and local tax rates vary — long before you can think of moving Bermuda or a similar tax haven. (The new tax law that went into effect this year does make the federal tax rate less, falling to 37% from the previous 39.6%.)

Having initially played 'little sister' to Mega Millions, changes made to Powerball in January 2012 and October 2015 meant that the Powerball lottery now consistently awards the biggest lottery jackpots in the world. In the year after the 2012 changes just under one in two (actual amount: 50 out of 104) Powerball draw jackpots were more than $100,000,000.

*The US Powerball is a standard lottery draw game based and operated from the golden State of California. The US Powerball has been making millionaires and multi-millionaires since its first drawing way back in 1992. With over 25 years of experience in the lottery industry, the Powerball, along with many other State lotteries, has broken through the final glass ceiling and transformed itself from an interstate lottery into a truly international lottery of global reach.*
