How small is the chance, that the number should be divisible by 19?
Well DJ, I’ll give you my opinion, for what it’s worth. I don’t have the skill to do advanced statistical analysis on this, but I can tell you, by starting with number one, 19 divides every nineteenth number evenly. It does so indefinitely. So, there are infinite numbers evenly divisible by 19. That is many numbers from which to choose.
It easy to tell that any random integer number has the odds of 1 in 19 (about 5.2631%) of being divisible by 19 (Wow! What a coincidence!)
Let’s say you took a number like the first million digits of Pi 3.14159… and multiplied it by 10^1000000 = 314159…. That means the converted Pi sequence will divide every 10^1000000 numbers evenly. With any finite amount of numbers, this Pi sequence is more rare than 19. However, if all numbers are considered, there are an infinite number of them, and because there are an infinite number of each they both have the same frequency. Yep, a one-million-digit integer will divide the same number of numbers as 19.
To explain more clearly, consider this. Let’s say you have two boxes. In one box are all integer numbers from zero to infinity. In the other box are all odd numbers one to infinity. It seems the box with all numbers has more numbers than the box with only odd integers, but they both have the same amount.
Assuming there is no introduced bias in the analysis or the assignment of values to letters, it might be statistically significant if 19 occurred well above chance. A Chi squared statistic is one method that will find unusual occurrences, used in conjunction with other texts, may confirm significant deviations.
One thing to keep in mind is that unusual events happen all the time. There are lottery winners all the time. Some of these lotteries have odds approaching 1 in 300,000,000, and there are multiple winners every year. It is the nature of humans, and we genetically enhanced chimps, to see patterns in anything and everything. We see human faces and animals in the clouds, all the time. We see Jesus, the Virgin Mary, and the devil everywhere, from burnt toast to the dust on a window. One time I saw a dog and cat in the clouds. I showed my dog and cat what I saw. They were decidedly unimpressed; probably because they see dogs and cats in the clouds all the time.
Most major religions have associated numerology, that is numbers or numerical sequences that are important to the belief are full of them. 3, 7, 8, 12 are all important numbers in Judeo-Christian religions. Don’t forget 666.

I play with this program. It’s an entertaining pass time. I introduced it to my father a few years ago, and he still plays with it. One day, about two years ago, I suggested he search for Colm (his name) and Satan. He told me he already had (I don’t know if that was true.) I suggested he use 666 as the starting index. He did and a few minutes later, he slammed his computer shut with a “Blŏŏdy hẹll!”
After a while, he finally showed me. In a neat, semi orderly crisscross grids, like a daily crossword puzzle, were these words: Colm will play poker in hẹll with his friends He will win every game always beating the devil.
When I offered that that is not too bad of a hẹll. He said if he wins every game, his friends wouldn’t be his friends for long. Of course, my father is no fool; he knew I had something to do with that unique presentation. He didn’t say anything. We rarely do. I grew up in a home where April 1st is celebrated with the same energy and sacred rites as Christmas and Easter.
Let’s return to finite numbers.
Here is a list of divisors for most of the numbers you used in your post
.
A quick review: Divisors are a list of integers that divide a number (evenly-no remainder).
All numbers have at least two –one (1) and itself. If the number only has two, then it’s a prime number. Composite numbers have three or more.

Do you see a pattern here?
Let me know if you do.
This question is on the current Sigma Camp’s Qualification Quiz for 2017
http://sigmacamp.org/sites/default/files/page_attachments/Qualification_Quiz_2017_Sigma.pdf
The camp is for children from ages 13 to 16 years. There are questions in all branches and disciplines of mathematics and science. Most of the questions seem very difficult – to me.
After a little thought, I realized the superlative wording of the question tends to send the solution seeker on a tangent toward a wild goose, instead of a correctly weighted elephant. To solve this though, one must think totally inside the box (instead of outside).
The solution:
The lightest elephant weighs 4000Kg. All the other elephants also weigh 4000Kg.
I’m glad elephants are used as prop for the question. Now, I will never forget.
Note to Blarney Banker: If you don’t understand this, I can try to dumb it down for you. However, I’d probably just be wasting my time and annoying the pịg.
Happy Birthday Melody!!
Recently, I was visiting your riotous birthday party of 2015. (There wasn’t a birthday party on the forum for 2016, for some reason). It seems like that party it’s still going on.
Zegroes has the funniest comment. “Im lack toast and tolerant anyways!......Chris your my new favriote moderator now”
Here’s a very late arrival to the party.
Great parties never end!
