As people here work in various jobs / professions they might know things from work or study no one here knows yet. this is what this topic is about.

what do you know that we have never heard of?

Eg: you don't need to be great at maths to be an architect

this is obvious to me but everyone says to me "i wanted to be an architect but i was bad at math,i can barely add"

Not its widely used name, but I suppose so.

I suppose if it was qualified as being in English, you are correct.

Eh, England?

Is that the UK. Questions as to what constitutes, a country? Usually member of the UN or such international Orgs, as per Richard Osman.

So England is not in Europe? Wow, that Brexit deal went through quicker than I thought it would.

In a 49 number lotto system the odds of picking 6 numbers are 1 in 13,983,816

Or to put it another way. Get a piece of rope or string, that's 39 feet long.
In a wide open area, arrange the rope or string in a circle, end to end, the best you can.
Get a single grain of sand or dirt (use tweezers!) and place it anywhere you wish inside the circle.
Get a second grain of sand. Close your eyes, and "disorient" yourself as to where the grain of sand is that you placed inside of the circle (have someone spin you around or something!).
While you're inside the circle, drop the second grain of sand from 1 foot up.
Your chances of hitting the first grain of sand with the second is roughly equal to the odds of "1 in 13,983,816."

Really? I would've thought that the odds of picking 6 numbers were 6 in 6? The odds of picking the right numbers is a different matter.

The odds of winning the Irish lotto (6 balls correct) is only slightly better with only 47 balls in it. 1 in 10,737,573.

But trying to win the Euromillions, which is effectively 7 balls, is simply pants
at 1 in 139,838,160,

Instead opt for winning 1m from just the 5 main numbers (1-50), ignoring the stars, which has odds of about 2m/1.

The city of Bratislava is the capital of Slovakia and the only capital city that is built where 3 countries meet; Slovakia, Austria and Hungary. They also have 3 totally distinct languages from three major language groups.

There are only about 15 capitals built on their countries borders.

Is the bolded but correct? It would seem to negatively affect the odds.

If the rope's length mentioned is a little unreasonable, for every foot above the circle that you drop the second grain of sand, you can reduce the length of the string by the same amount. For example, if you dropped the second grain of sand from a ladder 10 feet up, you'd need a length of string that is 10 times shorter than the one in #1, or a 40/10 = 4.04022 foot long piece of string.

It’s hard to get your head around just how small your chance of wining the lottery really is.

One example I like to help visualise it is, you’re about twice as likely to be able to guess someone else’s mobile phone number off the top of your head than you are to win the Euromillions.

Why, though?

Aren't the odds even worse if you have more numbers? (10, in a mobile phone)?

Also, I'd be curious to know how many chances (combined) you'd have to win any of the other prizes. I can't do the maths, I'm afraid.

The prefix can only be 1 of 3 tho. 086 086 or 085

So it's 3x10x10x10x10x10x10x10
=1 in 30,000,000

Ah, of course! That makes sense, thanks Quazzie.

For a phone number each digit can be 1 of 10. Let's assume it could be anything. So the number of possibilities is 10*10*10*10*10*10*10*10*10*10. For the Lotto if you were guessing the numbers in order it would be 47*46*45*44*43*42. Since you don't have to do them in order you can then divide by 6*5*4*3*2*1.
The number of possibilities in each case is important. Guessing a 3 digit number would be 10*10*10 or 1000 possibilities. Guessing 3 letters is 26*26*26 which is 17,576 possibilities.

Cheers for that.

After the 08x the next number cannot be a 0, so we have 3x9x10x10x10x10x10x10 = 27,000,000

FWIW Roscommon GAA are raffling a house worth €425,000. There is a max of 15,000 tickets and they cost €100.

The odds are the same as getting 4 numbers + Bonus in the Irish Lotto.

I used to play the Euromillions in a small syndicate of 4 people. I never understood why we played it and not the Irish Lotto as even sharing a €2,000,000 win is a life changing amount.

It can be, I know someone who's number starts with 0

But my maths are slightly off as I forgot about 083 numbers

It's 1 in 40,000,000

KERSPLAT!

089 too

089, 087, 086, 085 and 083. I don't think 088 is used anymore?

I don't think so, either. So, there's Vodafone, Three, Tesco, An Post, Lycamobile... are there any more?

Maybe some mathematician can help with this one...On the very odd occasion I buy a lottery ticket I always use the "computer" randomly generator numbers rather than picking my own. Am I further decreasing my likelihood of winning with this method? Are there odds against the 2 sets of randomly generated numbers being the same or are they 2 completely separate events that do not influence each other?
