Lottery One million tickets are sold for a lottery in which a single prize will be awarded a)If you purchase a ticket, determine your odds against winning. b)If you purchase 10 tickets, determine your odds against winning.

OpenStudy (wach):

a) If you purchase 1 ticket, your odds of winning are 1/1000000, so your odds of not are 999999:1 (got this by subtracting 1 from 1 million, making a ratio of odds) b) Same goes for 10 tickets: 1000000-10=999990 So, 999990:10 Hope that helps :)
