Sorry.


Oh and by the way, on the other question, apparently it's the egg (I love the LONDON, England bit) http://www.cnn.com/2006/TECH/science/05/26/chicken.egg/


LONDON, England -- It's a question that has baffled scientists, academics, pub bores and contributors to the East Dulwich Forum in East Dulwich, LONDON, England (OK I added that bit) through the ages: What came first, the chicken or the egg?


Now a team made up of a geneticist, philosopher and chicken farmer claim to have found an answer. It was the egg.


Put simply, the reason is down to the fact that genetic material does not change during an animal's life.


Therefore the first bird that evolved into what we would call a chicken, probably in prehistoric times, must have first existed as an embryo inside an egg.


So what is the meaning of life..... anyone?

Four (Peckham Rye-related) questions here. I'm going No, No, Maybe, Unlikely.


And did those feet in ancient time

walk upon England?s mountains green?

And was the holy Lamb of God

on England?s pleasant pastures seen?

And did the countenance divine

shine forth upon our clouded hills?

And was Jerusalem builded here

among these dark Satanic Mills?

Several years ago, I sat perplexed and silent and thinking in a pub after a so-called friend layed 'The Monty Hall Question' on me.


So, for anyone who wants to sit perplexed silent and thinking for a while, is desperately trying to not do any work and who hasn't heard it before, here it is:


Monty Hall, quiz show host, offers his contestant a choice of three doors, behind each of which a prize is hidden. Behind one door is a sports car, behind the other two, booby prizes.

The contestant selects a door, which remains closed.

Monty then opens one of the remaining doors, behind which he knows there is a booby prize.

The contestant is then give the choice of either sticking to his first choice, or switching.


Should he switch, or stick?

If you are the kind of person who entertains themselves by putting cats in boxes the car exists behind both doors and is also not behind both doors until you open one of them.


All possibilities are real and coexist until it is determined which one we experience.

Good question: sorry to be an anorak, but I have to bring this down to the mathematics of probability.


Statistically, answer should be switch - the original probability of getting the right door was 1/3. now that a booby trap has been eliminated, the odds of the other door being the prize are, technically, 1 - 1/3 = 2/3, not 1/2 and 1/2. So switch.

Re: Monty Hall, you definitely switch.


Think of it this way - if you stick, you have 1 door. If you switch, you have 2 doors. There is 1/3 chance the car is behind each door, so by switching you have 2/3. The fact that one of the 2 has a booby prize doesn't change anything.

The key is that the two choices you are given at each stage are not random events - the probability is affected by the fact that the host knows where the booby prizes are and knowingly removes one.


You have a 2/3 chance of choosing the booby prize in the first place and, if you do, switching guarantees you will win the car because the other booby prize has been removed. If you stick you keep your original 1/3 chance - switching doubles your chances of winning to 2/3.

i request more questions like "Donald Duck never wears trousers. but always wraps a towel round his waist after bathing - why?"

and less well known, mathematically and logically solvable problems like the three doors probability pooper..


what have you always wanted to know but were afraid to ask?

    • With fibre you are paying for the speed, which is the number, yours is 300 so if you did a lot of gaming, for example, you would want the fastest possible.  If it's just office work or maybe streaming on Netflix you likely won't need as fast, but, if there are a lot of people in your house all doing their own thing on different devices, then faster speeds are better.  I don't rely on my Wi-Fi much other than when I am using my mobile.  I use Ethernet cables to connect up everything, I Have one cable running from my router, along the skirtings and through a hole I drilled in the wall to another room.  I have attached the plusnet speed guide which gives you an idea of how it works.   
    • I'd reread what you posted and try to summarise.  It just comes across as a rant.
    • Just shows, to me, once proud to be a citizen of UK.. now.. well if we pay/contribute to services - nhs, police, fire etc and folk who have made this there home - no matter what creed or culture.. for the love c of God, can someone  please explain to me.. how we have working royals who like them or not, have tried and continue to actually support and make a change and then we have Andrew.. who just destroys everything.. not just him, or royalty but his own children..  I had great admiration for The Queen - and respect.. as have a huge number of people.. but.. these old traditions where gosh.. live rent free and can’t get chucked out until I believe 2070? From what I scanned..well he has and continues to have it all.. has to go thru what old rules? Etc.  doubt very much he has even kept the upkeep maintenance up on his abode.. and do the shite keeps on pulling up.. What has Andrew done for UK or for that matter since he was 20?? Do please tell me       Totally off topic, before anyone jumps down my throat.. I just do not get how anyone is proud to be British at this point in time. Whoever is in power, seems to be able to help themselves to the public purse with no redress at all - Covid is a great example of lining of pockets.. Millions  given to Rowanda, so one is led to believe, to help with refugee problem and one can’t get a plane load off!  I simply do not get it at all. Use of food banks in UK growing yearly, homeless as well, nhs, police, fire service etc all on their knees..        
    • Have applied the green roof at a number of properties and no issues you are concerned about detected. Have issues with cats defecating in the vicinity, however, they are not selecting the green roof specifically. Use decent compost, slow release fertiliser specific for green roofs, and lay it methodically not leaving blank patches. It looks amazing when cared for and adds value.
