Probability Question.

The same?

Assuming 3 identical idealised coins, the same.

Do you have to spin them ....if so you will need 3 hands !

t0sser.

I am a professional problemataterion and I say the odds at the same based on Einstein,s theory that time does really not exist.

need a fountain

I know that if I back three 1/1 horses to win three races at the same time one always loses.

The possibilities are:

HHH

TTT

HTT

HHT

Which makes it 1 in 4.

How can "a coin" become "them"?

WTF r u schmokin', Bruv???

The dude only has one coin.

Are you Money Tree in disguise, or summat?

It's one in 8. Probability 1/2*1/2*1/2.

you are all wrong:

statistically one of the unlikeliest things which have happened was when a professor was lecturing on probability and was tossing a coin - asking for calls of heads or tails: the coin landed - and balanced - on its side- to the astonishment of all.

Rate reply:

what about HTH then?

FFS!

Good question though... I too initially assumed it to be 1 in 8.

which it is

I would happily pay you 4-1 every time HHH came up if you would pay me 3-1 every time the result was one head and two tails

But there are only 4 possible outcomes...or am I losing my marbles?

hhh, hht, htt, hth, ttt, tth, thh, tht.
hth

but hht is the same outcome as hth?  isnt it? 2 heads and a tail.

The probability of outcome HHH is one in four.  The probability of sequence HHH is one in eight.   I think

yeah,  think you have nailed it....distinction between 'outcome' and 'sequence'.

It's 1 in 8, FFS, coin tossing is the most basic example you'll do day one if you ever look into probability!

Its' the probability of the first toss (0.5) being correct which then HAS TO have the next correct and so on, in order to render the complete sequence you're trying to find the probability of. 0.5*0.5*0.5.

Another example, if you had you a single suit of 13 cards, took a card, put back, shuffled, then took again, to get 3 aces in a row would be 1/13*1/13*1/13.

It's 1 in 8 Ozymandius.
Although there are only 4 types of outcome, hht and tth have a higher probability than hhh or ttt (as shown by kincsem). It's similar to rolling two dice where 7 is more likely than 12 or 2.

Combinations v Permutations.

ok, Foinavon, thanks, that's a helpful explanation.

HowieTheRookie only has ONE coin, ffs - how can he throw it thrice simultaneously?

^ and my shrink tries to tell me I'M nuts!

anybody want 4/1 then pm me



i too once had a coin land on its side, we never got a proper calculation of odds of it happening
very very small no doubt , getting on for 1,000,000 to one at a guess

Probability Questions:
1. If I put a pound coin in a pub urinal, then an average forumite came in, what's the odds the pound coin would still be there when he left?
2. If the answer to "1" was no coin, what's the odds the sink taps wouldn't have been used?

2!*2!*2!

1/8

i once rolled6dice 3 times and got all 6's - yes - 18 sixes 'in a row' - we all fell about laughing - and no- the dice were not 'loaded' - it was part of a game and didnt happen before or since....

get number crunching guys....
