1/12.56

wolframalpha.com/input/?i=probability of 50 successes in 100 trials with p=.5

There are 100! / 50! / 50! ways to hit 50 times and miss 50 times
there are 2^100 possible outcomes
chance is 100!/50!/50!/2^100

100%

Well done user.. Well done user..

HOWEVER -- what about this!?

I hit her 100% with my cock

100%

50% it either happens or it doesn’t

If she hits half of her attacks and she attacks 100 times shell hit 50 times.

So the chance shell hit 50 times is 100%

!?!?!?!

Same answer if we take into account machine inaccuracy
~8%

Attached: why do you read the filenames.png (387x100, 3.02K)

this is just a re-worded coin flip problem; the chance of getting Exactly 50 heads or hits in this case is 8%

Where does it say EXACTLY 50 times?

80%

? the coin flip problem is just a reworded sword girl problem

why is there a cos and where does the sum come from
please educate me mathfag-kun

It would be 1/2 squared, right? 25%?

It doesn't say at least or at most either you fag

It's exactly 53.97946187%
Binomial Probability

more like binomial retardity
faggot

brainlet

I was never good at Maths but if she has a 1/2 chance to hit, half of her attacks will hit...

Except the more you think about it, the more you realise this question isn't about her chance to hit but the chance that she will hit exactly 50 times, not 51 or 49. The amount of times would realistically be between 40-60, but figuring out the probability of all of those is another problem that I've never had to deal with.

whats the problem lucklet.

is this anime good? the only gambling anime ive seen is Kakegurui which is mostly coomer material but i mostly enjoyed the gambling parts

> 8.8817842e-16
Assuming the probability of each hit is independent of the last...
P(1hit) = 1/2
P(total hits) = (1/2)^100 # You would multiply by each independent trial
P(total Hits) = 7.8886091e-31
But we only need this to happen 1/2 of the time so we only calculate up to 50 trials
P(50 trials) = 8.8817842e-16 # Which is the answer
...also you have the internet: calculator.net/probability-calculator.html

Gambler's fallacy

You can just count how many different ways you can hit exactly 50 times
Like for 3 attacks there will be 3 configurations when you hit twice
(1 hit 0 miss)
110
101
011
Then you can count how many different configurations are possible.
for our 3 attacks case it would be
000, 001, 010, 100, 110, 101, 011, 111
Each configuration is as likely as another.
There are 8 configurations, 3 of them satisfy us.
What's the chance that the random configuration will satisfy us? That'd be 3/8
That's the chance to hit exactly twice in 3 attacks

Hope now you understand how this could be solved. Ask questions if not quite

it doesnt say exactly 50
if she hits more than 50 then she will have hit 50 times

>Kakegurui

Holy shit bro if you liked the gambling parts in that show go watch Kaiji right now

It's good. It's easily one of the best ones I've seen, no mater the genre.

i like it a lot but i think you need to understand/like mahjong to fully enjoy it.
you should watch Kaiji(its by the same dude and dont have any barrier) and its fantastic as well.

Probability math is the fedora of the math world

I'm a math A student, I know arithmetic, pi, prime numbers, square numbers, formulas, always been good at speed calculations et cetera; but probability math is definitely the stupidest.

Firstly because they always sound simple at first but ALWAYS end up being incredibly convoluted with bullshit that literally only applies to this specific question that you've never had to use before.
Secondly because people think that if you're good at math, you're good at probability.
Thirdly because it's 100% ha hathe most useless, redundant and least used category of math that you will ever need to learn. In no profession outside of gambling will you ever, in your life, need to apply it.

The short version is that the people who make these threads know the 3 facts I listed. Do not feel like a brainlet for being tricked by a simple layout, that's what they want. the people who make these threads are brainlets who want to feel smart. Feel free to ignore them. Take it from me.

What

You've only accounted for one configuration
that's the chance that all first 50 attacks will hit and the other miss
OR every odd attack hits
or some another way. But only that specific way
Any of them satisfy us, not just one

it's underlined so it's implied that it's exactly 50 times
if it was AT LEAST 50 then it would most likely be explicitly written as such

it's bait

at least 50 times or exactly 50 times?

Why the fuck would you waste your life on mathematics? Are you on the spectrum?

Ah, sorry, didn't read careful enough. You didn't calculate chance of one configuration
you've calculated the chance to hit 50 times in 50 attacks
sucker

thanks lads, gonna watch tonight

I remember that retard who came up with this puzzle. 500 post thread just calling him an idiot

it's not bait and im going to continue posting it until someone gets it

50%
either she does or she doesn't

I've been called worse

are you some kind of unemployed math teacher who can't help but annoy people with questions all day?

>math teacher

It only makes sense in his downs addled brain, don't bother

mustard gas

Do you mean minimum of 50 times, or exactly 50 times?

No but I enjoy these kinds of threads on Yas Forums and just wanted to make some content
