It's not practical at all, as this following article states: http://www.businessinsider.com/buying-every-powerball-ticket-2016-1 "According to Statista, JPMorgan Chase Bank has about 189,000 employees. That means that there are about 1,546 possible Powerball tickets for each employee. If each employee spent 10 hours a day buying and filling out Powerball tickets for three days, this would mean each employee would need to fill out about 50 tickets per hour."Xianjun Donghttps://www.blogger.com/profile/16940344808359020274noreply@blogger.comtag:blogger.com,1999:blog-12445049.post-44710163533981608072016-01-15T10:50:55.463-05:002016-01-15T10:50:55.463-05:00That's a really interesting point!

I would say that buying 292 million tickets (of which only a few win) would definitely incur a lot of expense (i.e. loss) in my book. <br />I wonder if there's a hedge fund buying all the numbers right now. I hope they sent the intern to wait in line.... which makes me think that perhaps your analysis doesn't account for the acquisition cost of each ticket.Genehttps://www.blogger.com/profile/14036049106224244818noreply@blogger.comtag:blogger.com,1999:blog-12445049.post-70934978135010549542016-01-14T23:51:47.304-05:002016-01-14T23:51:47.304-05:00I guess you can if you loss a lot and keep the evi...I guess you can if you loss a lot and keep the evidence.
