So, if I am correct in assuming "relatively prime" simply means that one number is not evenly divisible by the other, then here are my initial thoughts:
You have a 1/n chance of first drawing a "1"...in which case, you will win automatically (1/1 chance)
You have a 1/n chance of first drawing a "2"...in which case, you will win if the second number is even OR a factor of 2 (aka: 1)
You have a 1/n chance of first drawing a "3"...in which case, you will win if the other number is a multiple of 3 OR a factor of 3 (aka: 1)
You have a 1/n chance of first drawing a "4"...in which case, you will win if the other number is a multiple of 4 OR a factor of 4 (aka: 1 or 2)
...
You have a 1/n chance of drawing "x"...in which case, you will win if the other number is a multiple of x OR a factor of x
So let FACT(x) = number of factors of number x...we can then write our chance of winning to be:
SUM (1/n * (1/x + FACT(X)/n)), x=1..n
Which clearly just get worse and worse the more balls there are in the bin...in which case, I would only take the bet if there were visibly "few" (less than 20 or so) balls in the bin.
Now, I suppose my above reasoning only holds if we assume all the numbers 1n are in the bin...if you have completely random/arbitrary numbers...then, my reasoning probably completely falls through. Again, just my first thoughts. I am also curious to see what others come up with.

I just saw this puzzle...it's pretty awesome...
All you really need to do is notice that the string ends with "=="...which, if you know anything about encodings, is a common ending for Base64 encoded strings.
So, just plugging the string into a Base64 decoder, you get the result that was flagged as the answer.
Really neat puzzle...simple if you get that first step...and props on the ASCII art! 1

Sunflower? Seems a little too obvious, and I don't think it fits all of it...

(2^{n}1) + ((n^{2}n)/2) + ((3^{n+1}  2^{n+3} + 6 + (1)^{n+1})/12)
Validated out to n=5 so far...I'm pretty sure on the first two parts of that formula...it's the last/third that I'm a little questionable on...and if that's correct, here are the values up to 9:
n=1: 1
n=2: 4n=3: 12n=4: 31n=5: 81n=6: 218n=7: 610n=8: 1753n=9: 5127 
6: no  after putting a triangle in each corner (which must be done to fill the corners), you must put another triangle with its edge along the edge of the board, which then leaves you with 3 separated hexagons left
7: no  28 hexagons on the board is not divisible by 38: no  again, after putting the triangles in the corners, you will end up with 3 hexagons that left over that can't be covered with a triangle
9: yes
I can give more detail if needed for any of these...but the OP didn't actually ask for "why or why not..." so...

Problems like this always SEEM so straightforward, but the answers are always a little shocking to see:
New weight: 50lbs
Weight of the 1% water lost: 50lbs
Weight of the 98% water remaining: 49lbsFirst let's do the obligitory/obvious initial analysis of the original amounts:
0.99 = water weight / total weight
0.99 = water weight / 100
water weight = 99lbs
So, now we need to find the new weights:
0.98 = new water weight / new total weight
we know that the new water weight is: 99  water weight lost
and we know the new total weight is: 100  water weight lost
Let x = water weight lost
This gives us the equation:
0.98 = (99  x) / (100  x)
98  .98x = 99  x
0.02x = 1
x = 50
This means the water weight lost was 50lbs...so using that, we can find the answers above. We can certainly validate this answer by showing that if we have 50lbs of potatoes, and 49lbs of it are water, we indeed have 98% water weight, and both the total weight and water weight decreased by the same amount (50lbs)...or another way of seeing that is that the original weight of the nonwater parts of the potatoes were 1 pound (100  water weight)...since that does not change after the water evaporates overnight, the end result should still have 1 pound of nonwater weight...which we do have (50  49).

Let x = mathematically "correct" answer...then the answers above come from:
if x < 10, then x...
else (x % 10  (FLOOR(x / 10)  1)) 
The calendar repeats itself AT LEAST every 28 years (could be every 5, 6, 11, or any combination of those...)...so if we find one year that matches the above calendar, we would be able to find infinite many...
With that being said, the NEXT year that fits this pattern will be 2017...and the LAST one that did was 2006 (notice how that is 11 years apart, as mentioned above)...
Here are the years in the 2000s that fit this pattern:
2006, 2017, 2023, 2034, 2045, 2051, 2062, 2073, 2079, 2090
And here are the years in the 1900s that fit this pattern:
1995, 1989, 1978, 1967, 1961, 1950, 1939, 1933, 1922, 1911, 1905
...That is, unless I'm missing something in this puzzle that helps us pinpoint an exact year...and that I'm interpreting the puzzle correctly :c)

I can explain the process that I used in more depth if needed...but it's really not too difficult if you begin by choosing the first number in the randomly generated number and start filling in the inventory number step by step based on that...I started this process with the number starting with 9 and worked my way backwards, but you could do it starting at 1 and work your way up.
As you do that, you'll find that the generated number can't start with a 9, 8, or 7...you eventually get to numbers that start with 6:
6 ? ? ? ? ? ? ? ? ?
? ? ? ? ? ? 1 ? ? ?
6 ? ? ? ? ? 1 ? ? ?
? 1 ? ? ? ? 1 ? ? ?
6 1 ? ? ? ? 1 ? ? ?
? 2 ? ? ? ? 1 ? ? ?Have to change our generated number to match the inventory number...
6 2 ? ? ? ? 1 ? ? ?
? 2 1 ? ? ? ? ? ? ?
6 2 1 ? ? ? 1 ? ? ?
? 2 1 ? ? ? 1 ? ? ?
6 2 1 ? ? ? 1 ? ? ?
6 2 1 ? ? ? 1 ? ? ?

This is actually a subject I find really fascinating...just don't try your method with 196, or any of the other proposed "Lychrel Numbers"...you might be there for a while.

Pickett,
can you come up with a different set with smaller magnitudes (as in absolute values) for a, b, c, and d?
But my first answer still solved the OP...
a=2
b=2
c=4
d=4
or
a=2
b=2
c=4
d=4

not sure if it's the smallest yet, but it's probably getting pretty close at least:

.0123457689
.0142675398
.0196582374
.1203456789
I'm thinking this HAS to be the smallest possible sum...here's why:
The smallest valid number we can use is .0123456789
So if we do that 9 times (illegally, of course...but just doing it for the sake of demonstration), the sum would be .1111111101...which would be the absolute minimum value for the 10th number.
Obviously that isn't a valid number (according to the constraints of the problem), so the closest number we can get to that absolute minimum would be .1203456789
Which is the answer I have above.
Now, I there are multiple WAYS to get that sum, but it should be the minimum sum.

First off, expanded out:
P(x) = x^{8} + 2ax^{7} + (a^{2} + 2b)x^{6} + (2ab + 2c)x^{5} + (2ac + b^{2} + 2d)x^{4} + (2ad + 2bc)x^{3} + (2bd + c^{2})x^{2} + 2cdx + d^{2}
So that means all 9 coefficients are:
 (1)
 (2a)
 (a^{2} + 2b)
 (2ab + 2c)
 (2ac + b^{2} + 2d)
 (2ad + 2bc)
 (2bd + c^{2})
 (2cd)
 (d^{2})
Since we know a, b, c, and d are nonzero...that means coefficients 1, 2, 8, and 9 can never be 0. Therefore, the theoretical max would be 5 coefficients equaling zero:
 (a^{2} + 2b) = 0
 (2ab + 2c) = 0
 (2ac + b^{2} + 2d) = 0
 (2ad + 2bc) = 0
 (2bd + c^{2}) = 0
By equation 1, we can see that b = (a^{2}/2)
Then by substitution in equation 2, we can find that c = a^{3}/2
Then using substitution in equations 3, 4, and 5 we find the values of d...which end up being:
By equation 3: d = (5a^{4}/8)
By equations 4 and 5: d = a^{4}/4
Since there are no situations where (5a^{4}/8) = a^{4}/4 are true (except when a = 0, which we know it doesn't), we have to choose the one that gives us more valid solutions, which is that d = a^{4}/4...which means that we can have a maximum of 4 coefficients that equal 0 in this expanded equation (which means the minimum nonzero would be 5): a = x
 b = (x^{2}/2)
 c = x^{3}/2
 d = x^{4}/4
We now need to find values of x that give us integer values...so an obvious answer would simply be x=4 and/or x=4, which gives us these two solutions (resulting in 4 zero coefficients, aka 5 nonzero terms):
SOLUTION 1:
a = 4
b = 8
c = 32
d = 64SOLUTION 2:
a = 4
b = 8
c = 32
d = 64
