statistically, any ticket has a chance of winning. i used to buy 1 ticket/week, or sometimes 10 tickets on a whim, and once won the junk item by doing that after many many weeks.
i did the maths on my total tickets bought vs current LAH for the junk prize and discovered i had purchased the world's most expensive peacock jumping spider.
i don't buy tickets any more.
if you do the maths on what percent of total tickets you own, you now have your chance of winning.
at time of writing, this week's raffle has 147030 tickets. that's pretty low, but we're not even half-way through the raffle yet so that makes sense.
147030/100 = 1470
that's 1%
in order to have a 1% chance of winning
right now you'd need to buy a minimum of 1,470 tickets. by the end of the raffle, that number will be a lot higher.
let's assume i buy 150 tickets, because that's the amount you can buy 75kt (maxing the fairgrounds for one day)
100 is 0.1% of 147030
(according to
this calculator, i can do it manually but it's not worth the effort. the calculator is correct)
i have a 0.1% chance of winning
any prize with my 150 tickets. but...i want the dragon.
there are 125 prizes this week, including the dragon.
1/125 = 0.08
assuming i beat the odds and get drawn, i have a 0.08% chance of winning the one prize i want, the dragon.
if we multiply the odds of being drawn at all (0.1%) with the odds of getting the dragon (0.08%) we get
0.1 * 0.08 = 0.008
(which is hopefully obvious to anyone old enough to play flight rising)
that's a 0.008% chance of getting the only reason i'm buying these hypothetical 150 tickets
and again, these numbers are low because there's currently a relatively low number of tickets bought.
any time i find myself tempted by a dragon prize, i run the maths again and am reminded that i am better off saving my money to
buy the prize after it is sent out. because it will probably cost less than buying enough tickets to win it anyway
and if you WANT the junk prizes, the same goes there too. by the time you win something, you will have spent more money on tickets than you would have spent on that thing.
roundsey is only worth it if you can buy SEVERAL THOUSAND tickets to make the odds vaguely reasonable.
