Guys, solve this problem. Imagine a class with 10 people in it...

[busydude]

With 5 men and 5 women, what is the probability that two people fart at the same time?

P. S. This is not a homework problem.

 

[tynopik]

well first you can simply to a class of 5 men since women don't fart







they toot

 

[Murloc]

insignificant

 

[DAGTA]

Is this a class of chili judges after a contest?

It depends if the women are hot or not as men will hold it in if they are hotties.

Also you have to assume one of the 5 men is gay so one less likely person who would fart as only manly men have gas.

Main question is:

Is it a fart?
or
Is it a queef?

time is continuous. the probability of any two events happening at the same time is 0.

 

[silverpig]

time is continuous. the probability of any two events happening at the same time is 0.

That's only if the events are instantaneous. We're talking about events with some duration, so "at the same time" means they overlap in duration somewhat.

hmm... i'll have to ask a professor what the appropriate distribution for modelling it would be.

Planck time?

(Though if we're going to a time that brief, the probability would indeed be so close to zero that it would make no difference.)

That's only if the events are instantaneous. We're talking about events with some duration, so "at the same time" means they overlap in duration somewhat.

The question needs to be clarified: Must they simply overlap in duration? Or are they to be initiated at the same instant?

hmm... i'll have to ask a professor what the appropriate distribution for modelling it would be.

And indeed, the definition of "fart" would need to be defined...right down to some rather "specific" details concerning behavior of lightly pressurized gases, and the physics of a sphincter.

 

[Fayd]

Planck time?

integral of any distribution (or any function) from a given point to the same given point is 0.

no, no, events of variable duration and potentially random occurance will be sufficient.

 

[Engineer]

Not this shit again...

 

[CPA]

That's only if the events are instantaneous. We're talking about events with some duration, so "at the same time" means they overlap in duration somewhat.

So, you're saying you have to factor in the length of the fart? A long wet one versus a short dry one versus a multiple fart.

 

[GagHalfrunt]

Odds are pretty close to zero, so no sense trying to use that as an excuse. If you let one rip everyone is going to know it was you and you alone.

 

[IronWing]

SIGMA[(n-1)/(n!-(n-1))] N->(n-1)

 

[Red Squirrel]

The odds increase as time increases as more chance was given for it to happen. Theorically if they are there for infinity the odds are probably 100% as it's bound to happen at some point in time. At least if you don't get into the details like the fact that they need food and stuff.

Wrong, you just point to the guy next to you and blame him.

One detail you forgot that the OP posted.

What is the probability that two people fart at the same time?

So that's 10 people total. It could be 1 minute, 1 hour, 1day, .... infinity.
2 people out of 10 farting at the same time, probably approaching zero%. One could fart 1 second ahead and stop, the second could start a few milliseconds after 1st person stops... but that wouldn't be the same time. ^_^:biggrin: WTF is this question about?

 

[ch33zw1z]

what did they eat recently?

Is one person holding it until someone else farts so they can pass the blame?

Yeah, but what I mean is with random farts at random time, over a long enough period, it could happen that two happen at once, and the longer this time period is, the higher are the odds that it does happen at same time, thus why I said if we measure to infinity then it's 100% because it's bound to happen at some point in time where two farts happen at same time. Now farting at same time could mean different things, start at same time, or simply overlap. One might start before the other but if the farts are long enough they might still happen at the same time.

Now if this was a computer simulation, and was single threaded, one could argue that it is impossible for it to happen. :biggrin:

Ok, I am not worried about them originating at the same time. I guess overlapping farts is the main reason sensible thing to calculate.

 

[Fayd]

I just had a thought.

for simplicity's sake, until I talk to a professor and get this sorted, let's assume that on average a person is expected to spend lambda time per hour farting. we'll also assume that people's farting is independent (one person's farts does not affect another person's farts)

i'll finish this thought tomorrow.

Come on man, I needs an answer.

 

[Krazy4Real]

not enough farts with only 10 people... need more farts per minute.

Unless this guy is in the room, then I'd say chances are high.
