/sci/ - Science & Math

reported

I encourage everyone else to do the same.

actually it's 33.333333...

Let's say there are 15 questions with 4 choices each. Let's also say there are 3 lifelines: call-a-friend, 50-50, and ask-the-audience.

For each of the 15 questions, there is only 1 correct answer, and 3 incorrect answers, so immediately your chances are 1/3 = 33.34%. You can use each lifeline once. Using phone-a-friend, let's say gives you a 95% chance the person you call is correct. So 1 question is 95%. Similarly, we can say ask-the-audience gives you a 95% chance. Finally, 50-50 will remove 2 wrong answers, so you have 1 right answer and 1 wrong answer, so you basically know the answer. To recap:

Question 1: 33.34%
Question 2: 33.34%
Question 3: 33.34%
Question 4: 95% <--- ask-the-audience
Question 5: 33.34%
Question 6: 33.34%
Question 7: 33.34%
Question 8: 33.34%
Question 9: 95% <--- phone-a-friend
Question 10: 33.34%
Question 11: 33.34%
Question 12: 33.34%
Question 13: 33.34%
Question 14: 33.34%
Question 15: 100% <--- 50-50
Total: 690.08%
Divided by 15 questions = 46.00%
So basically, it's more a less a game of chance, but more than half the people on the show will lose, so it's not very fair. That show is making tons of money off of people.

3/10

OP, if you want to troll /sci/, you need to go beyond misusing elementary statistics. If you misuse something more advanced it will be much more effective.

>>4911197
it doesnt work that way dude, only one wrong question will make you lose

example, after 7 questions your chances are:

(1/4)^12, which, i am guessing, is a pretty small number

it would be totally broken if you had 50% chance of winning just by choosing random answers

(considered phone call etc 100%)

>>4911211
>implying religion == something more advanced

>>4911212
>>4911211
Are you people joking? This is basic math.

>>4911212
woops
1/4 ^12 would be after 12 questions
1/4 ^7 after 7 questions

you guys, you cant make medians with this stuff

>>4911222
Nope, that's wrong, pick up an elementary school testbook

>>4911224
so, you are suggesting, if i throm a dice 4 times in a row, my chances of getting 4 ones are :

1st throw: 1/6
2nd throw: 1/6
3rd throw: 1/6
4th throw: 1/6

Total 4/6 -> /4 -> 1/6

thats plain wrong

itd be (1/6)^4

starting to realize sci is not actually good at anything

>>4911233
The chance would 1/5 for each throw. You must be trolling. This is elemenatry school math.

>>4911234
oh yes, sorry i forgot dices have five sides

OH WAIT THEY DONT YOU FUCKING STUPID TOOL

>>4911242
Exactly. They have six and you idiot can't into basic probability.

If you consider every other question as IID and you do not include using lifelines in your calculations, they it's pretty simple - you've got 15 questions, each has a probability of success = 1/4 (if you don't know the answers to any of them and you just count on your luck throughout the entire game).

That's a simple Bernoulli distribution.

>>4911234
HAHAHAHAHAHHAHA

>>4911248
>each has a probability of success = 1/4
Stopped reading there, 0/10

>>4911245
negative IQ detected

>>4911262
Where? You mean your own person? I agree.

>>4911254
are you seriously trying to use a Monty Hall's problem reasoning for the simplest probability calculations?

>>4911265
What are you? 10? 11?

Please go back to 3rd grade where you learn how to do this trivial garbage

>>4911181

You know, the game COULD in fact be more about how smart you are than luck. It's only luck based if you know none of the questions. That being said, OP is a fag.

Every day you fuckers get trolled by this

/sci/ really is the easiest board to troll

>>4911277
It is not a game of intellect, wisdom, or luck. It is a game of chance. See >>4911197 for a proof.

>>4911264
okay, ill explain in case you are not trolling
chance of getting a 1: 1 out of 6 (six is the number of sides)
chance of getting a 2: 1 out of 6
chance of getting a 3: 1 out of 6
chance of getting a 4: 1 out of 6
chance of getting a 5: 1 out of 6
chance of getting a 6: 1 out of 6

chance of getting any number: 6/6
chance of getting any even number (2,4,6): 3/6

whats your take on this?

>>4911278
Every. Fucking. Day.

>>4911288
Chance of getting a one:
There's one 1 and 5 non-ones.
Probability is 1/5.
Educate yourself, retard.
It's lower than highschool math.

>>4911293
that is not the way you "write" probability

it goes like this:

(events considered)/(total number of possibble events)

not

(events considered)/(total number of possibble events-events considered)

Using your logic the chance of getting tails in a coinflip is 1/1 --> 100%

>>4911317
Please go to school. You got it wrong.

>>4911344
As the gambler and physics student i assure you i got it right and that you have no way of proving me wrong

In the meantime stick to your ad hominem shit and keep being an ignorant fuck

>>4911371
You realize this a troll thread that gets posted 3 times a week, right?

>>4911377
Ive been here a day, and i have seen enough stupidity to believe the dude might not be trolling

>>4911386
What was the stupidest post you've seen today?

>>4911386

>Ive been here a day

and it shows

>>4911371
>freshman undergrad physics student cannot recognize trolling

>>4911389
There was one in which OP tried to do logic with any sort of education and thought.he had accomplished sth worthwhile

The archer and the kid with the apple thread had some crazy stuff too, probably on page 4 or 5 by now

good god sci, you people are funny. every day i come on here there is a new way someone tries to argue with this.

>>4911433
Is being funny just a game of luck?

Is it a hard science or does it experience qualia?

Can Jacob Barnett do it?
