Last week the powerball set a record $1.5 Billion jackpot. That's pretty darn big.
The odds of winning are 1 in 292.2 million.
That means if you invested the average US median income, $51,940, into buying tickets, you would have 25,970 tickets. This improves your chances to 25,970 in 292.2 million
In perspective that increased your odds from 1:292,200,000 to 25,970 in 292,200,000.
BUT, don't start dividing 292,200,000 by 25,970. You didn't increase your odds from 1:292,200,000 to 1:11,251. Nope, you have 25,970 chances with 1 in 292.2 million odds tickets. The odds for each ticket stays the same.
