[Request] You're not winning the lottery, guy.
I was in a discussion with a co-worker about the lottery. He plays once a week and has for a number of years. I mentioned that I didn't. He said he always plays the same numbers every week, not because they're lucky, but because he believes that playing the same numbers every week somehow increases his odds of winning. I couldn't get any sort of rational explanation for this and I tried to explain to him that because every lottery drawing is from all the possible numbers available in the drawing, he has the same possibility of winning regardless of the numbers that he plays. Only if he bought more than one ticket with different sets of numbers, in any one drawing, did he actually increase his chance of winning. He refused to believe that I was right and he was wrong. Neither of us really has the math to justify our opinions. Can someone help prove me right?

[Request] My friend asked if an object 7.5x the Mass of Earth could replace Jupiter and still hold it's largest moons, and I set out to do the math. Can anyone here smarter than me point out if there's anything wrong?
This assumes this object remains the same velocity and is in the same position that Jupiter was in. This also assumes it will keep the same orbit as well. Also sorry for the terrible handwriting.

[Request] What is the size of the trolls in this Swedish children song?
Translated it goes like this:
Once there was an ugly, old and wicked troll,
who came to this country in a hot-air balloon.
He settled down in Småland,
with his head on Åland,
and his feet, at the very same time, in Lund.
And the old troll had a troll wife, too.
Her nose was as big as all of Amsterdam.
She cooked up the food
and served it on plates,
a cake made out of sand,
as big as all of Svealand.
And the old troll had an old tomcat,
who was as big as the whole Kattegat.
Far away in Yokohama,
you could hear him yowling,
and his tail was as round
as the whole Öresund.
And so this little tale ends for now,
for the trolls have already left in their balloon.
Now they must be near the North Pole,
or perhaps right in the middle of the Sun.
And dear friend,
they'll never come back again.
I can see that the geographic references is both here and there but could the size of the trolls be decided?

[Request] In Ghosts (USA), can we calculate the average rate of death and average time spent as ghosts?
We know that about 5% of deaths result in a ghost, and that ghosts haunt the place they died for some time before moving to the great beyond.
At the time of the show, the haunted house features ghosts with the following death dates that have not yet moved on: 1007, 1513, 1777, 1891, 1895, 1928, 1950, 1969, 1985, 1987, 2000. There are also two groups of ghosts we could include, but who would dominate the data: 1777x3, 1832-1870x11.
Assuming a normal distribution, can we deduce how often new ghosts appear and how often they move on?

[Request] if the powerball lottery was hidden in a building instead, what are the equivalents of guessing the right building/home?
For example, getting 1 red powerball number gets you 4$, a 1 in 38 chance
The buildings are something close to
100 million single family homes (SFH).
5.2 million multifamily residential buildings (everything from duplexes to large high rises), containing 40 million housing units.
5.5 million commercial buildings.
350,000 industrial buildings.
240,000 military buildings.
So the question is, what powerball odds are equivalent to things like “guessing the right state” or “guessing the right street” or “guessing the right county”

Of a well suited holomorphic topology
Then , there's an oscillating series of the infinite end case, hence thus reasoning is a oscillating series

[Request] How long do we reckon?
Every thousand years
This metal sphere..
Ten times the size of Jupiter
Floats just a few yards past the earth..
You climb on your roof
And take a swipe at it..
With a single feather
Hit it once every thousand years..
Til you've worn it down
To the size of a pea..
Yeah, I'd say that's a long time.
