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.

If I know all the answers it isn't luck.

This is the most retarded thread i've seen all week. One out of four is 1/4 = 0.25 = 25%.

Are you stupid? It's 1/3, you have one choice right, three wrong. Go back to first grade kiddo.

Yes, I'm sure; it's stale troll copypasta. Also, very funny on the samefag, but you're trying too hard.

>calls himself "mathfag"
>derails a thread on probability theory

YOU are trying too hard.

>>4923765
A TROLL thread on probability. There's a difference between trolls and threads with merit.

>>4923758
I don't know what you're talking about. This is a legit, unsolved problem in probability theory, and has never been posted on /sci/ before. This game show does not follow a simple Bernoulli distribution of questions.
