Is who wants to be a millionaire just a game of luck?
I mean, there's 33.34% chance of being right unless the person happens to know the right answer, and lifelines can only get you so far into the game.
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.

GTFO

did you wake up from a coma or something? this pasta is ancient, we don't post it anymore.
If there's only one question, there are four possible answers, and one of them is correct. Chances of guessing the correct one = 25%.
If there are two questions, there are eight possible answers, and two correct answers. Chances of guessing them both: 25%
If there are 15 questions, there are 60 possible answers, and 15 correct ones. Chances of guessing all 15: 25%.
>>7875132
Wow you're out of touch with the times man
the most modern theory of probability is that every event in the world has a 50% chance of happening: it either happens or it doesn't.
>kek
I'm glad it's been so long since I saw this. Adding up all the percentages is fucking genius and I had forgotten about that.
>>7875345
You obviously don't know the game.
You can also decide not to answer, since you might lose money if you're wrong.
Win, lose, quit. So 33.34%
>>7875132
How long has this been a pasta?
Must be at least 6 years?

Saying its 46% isn't really fair because
A) You didn't factor in how nervous the person is
B) You didn't factor in the extra 5% for the house advantage
For every question, you are either going to answer it correctly or incorrectly. That means that you have a 0.5 probability of getting it correct (i.e. a 50% chance of winning a billion dollars every time you roll the dice).
Because there is more than 1 question, every answer you get right increases the chance that you will get the next answer correct (due to the law of the gambler's fallacy), and so assuming you can get the first question correct - because they are generally the easiest - the probability of getting the 2nd question correct is increased to 75% (0.5 + 0.25 probability) and so forth until you get to 100% just before you guess the last answer correct.

That's not how probability works
It's a .25^15 chance of winning by pure guess
What's the taxes on these shows?

Either you win or you don't. 1/2 = 50%. Go back to Math 101 fuck boy.

How do you calculate it when there are situations when one of the 4 answers is obviously wrong?
i.e. Which kids film doesnt have a lion in it?
a. The Lion, the Witch, and the Wardrobe
b. The Lion King
c. Shrek
d. Harry Potter
>>7875132
Rick Rosner go to bed
>>7876250
The Lion, the Witch, and the Wardrobe or The Lion King doesn't have any lion in them
lions are defined as an animal that cant talk. Since those two animals can talk they are not lions.
>>7877134
Animals can talk, go to zoo and watch lions go RAWR!!
>>7875439
You've got your maths all wrong. The chance of losing your money is 1:2, so it's 50 %. Thus, the other two must have a combined probability of 50 %. So it's actually 25 %.
>>7875132
It's 50%. You win or you loose. It's that simple.
/sci/'s oldest troll pasta persists for over a day,
where's the moderation?

What's the right answer?

Didn't Shrek fight a lion in the movie?

>lions are defined as an animal that cant talk
Every animal that can't talk is a lion?
>>7878760
There were gryphons in Harry Potter but I don't remember any lions

Where are you getting 33.34% from? It's one 1/4 not 1/3
>>7883995
That's the same thing
>>7885710
1/4 and 1/3 are not the same thing
You're playing a game of who wants to be a millionaire.
The question is what color are roses.
Your options are
A red
B blue
C yellow
You select your answer and Regis removes a wrong answer.
Do you switch your answer?
>>7887184
Would they ask a simple obvious question like that?
>>7875144
Those who fail to acknowledge history are doomed to repeat it.
Fucking hilarious. Had me near tears.
>>7875132
depends on the percentage of how accurate your percentage list is.
>>7885710
What's the same thing? I suggest that the probability is 1/4 not 1/3.

>That show is making tons of money off of people.
The show makes money from ads not contestants.
>>7888564
They also make a lot of money from show related merchandise.
>>7876250
They're all obviously wrong. The "lion" in LWW is actually God, and Mufasa/Scar/etc are all manifestations of Simba's own vengeful emasculated id. The probability is thus infinity percent, because we have 4/0.

This ancient pasta thread has been alive for 7 days. In conclusion, there really are no mods on /sci/, let alone janitors.
>>7875132
Wouldn't four choices each give you a 25% chance of answering correctly?
>"There is only 1 correct answer, and 3 incorrect answers, so immediately your chances are 1/3"
No, there is one correct answer out of four total answers: 1/4
