we ae in the internet, on gaming community, I guess basic PC usage (as basic as to run a Calc app) is a common knowledge here.
As for probability theory - not really - if it was to be about multiiple chances, conditional chances etc - yeah sure, but knowledge of 1 from 10 being 1/10 th is elementary-school level and the beggining of it actually

Grade 4? really? lol at murican education system ;p I've had fractions introduced at the end of 2nd grade and more complex operations, like dividing fractions by each other or finding a common denominator in 3rd. 2-3 grade out of 8 is a beggining of elem school.

There is a lot of variance within U.S. schools. Public schools usually introduce fractions at the end of 2nd grade with manipulation (+, -, *, /) in 3rd grade, but this can be delayed until 4th grade if the situation requires it. Private schools tend to push the curricula faster as they have a less diverse student population. Public schools pretty much have to accept anyone that applies, including those who don't have any prior schooling and/or knowledge of English.
Public schools usually go Kindergarten - 6th grade with 7-8th grades being Junior High School and 9-12th grades being High School. Some schools group 7 and 8th grade with the primary grades (K-6), and others group 7-9th grades. Private schools can do anything they want in regard to grouping. In the end, it mostly depends on location/student population and budget.

I'll have to agree with Zelg on this one. It's just basic math, nothing very complicated. :P

The vast majority of the population, while adept at simple maths, are not so good at figuring out the required computations (which is why so many people in this thread were in error). This is why so many of us hate "word problems."

wow, good job. I myself am not a very good breather. sometimes I forget to do it and just start choking on nothing.

The way I see it... 1 in 200 gives you 0.5% chance, 5 in 1000 gives you 0.501% chance (1/1000+1/999+1/998+1/997+1/996). 5 in 1000 only gives 0.5% chance if one person can win all 5 copies.

^hated that middle school question. You can tell, since i still remember it plus the day.

Edit: As Sewaz corrected me, my calculations were slightly off. Since we do need unique picks, the chances are the same. The original calculations assumed that the same number could be picked more than once.
Possibility of not winning the 1 copy with 200 entries is 199/200. Possibility of winning it is 1 - (199/200) so 1 in 200, or 0.5%
Possibility of not winning the 5 copies with 1000 entries is 999/1000 998/1000 997/1000 996/1000 995/1000 which is equal to ~197/200.
Possibility of winning it is 1 - (197/200) so 3 in 200, or 1.5%. 3 times higher than the 1 in 200.

True, slight miscalculation.
Chance of not winning is 999/1000 998/999 997/998 996/997 995/996 since the same number can't be picked twice. So chance of not winning is 995/1000, so 199 in 200.
The difference is not that they are picked at the same time, but that they must be unique.
Still, thank you for correcting me, fixing previous comment.

It would be essentially the same. I don't know how SG calculates, but assuming unique winners are chosen, which I believe is the case (either because of reroll for duplicate winners or exclusion of winners from the pool for the next draw), you should have the exact same odds unless there's a quirk with the selection mechanism.

the only think you should have is luck, you should be lucky as hell... once I had 549 entries on 726 and I lost, I watched the winner of the giveaway and he only put 10 entries in it... How unfair it was ^^'

You have an near unnoticeable higher chance of winning the 5 copies of 1000 entries @ a .501% chance in relation to the 200 copies at 1 entry at .5% chance.

5:1000 is 1:200
However in the off chance of a re roll, the new odds would be;
1:199 vs 1:995

I'm happy to win anything on this site, chances are really small whatever the numbers are, like in lotteries like Lotto or EuroMillion. I have 3,490 entries and i won 12 games using the site commonly practically twice a day in 6 months, but i only enter the giveaways for games that really want my mate have 5000 entries and he got only one game this is unreal bad luck for him. But he is entering any giveaway just too zero his points, maybe this is the point site see what you have on your wish list and sometimes it gives you what you want. :) Mathematics poopmathics. Chances are the same for everyone on this site whatever the numbers are.

I nearly failed my statistics class, but shouldn't the winning chances of a five-copy giveaway have these factors:
1/1,000
1/999
1/998
1/997
1/996
Just dividing 1,000 by five can't be right. There are ~1,000 entrants per draw, not 200.

5 in 1000 gives a better chance of winning, but the difference is negligible. Also, probability does not determine success. In the long run, winning is simply a matter of perseverance.

2nd option obviously, as you could win that game 5 times instead of just once !!!

Which gives you higher chances of winning, or are they the same?
5 copies of game, but 1000 entries
or
1 copy of game, but only 200 entries.
