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 happen to know the 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.

Out of 4 possible answers with 1 correct, how do you come to the conclusion that you have a 33.34% chance of getting the right answer?

Your maths is so terrible it's actually making me cry

>> No.5408800

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%.

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.

Is finding a gf just a game of luck?

I mean there's a 0.0001% chance she isn't mentally retarded, a 0.001% chance she doesn't have a boyfriend, a 0.000001% chance she shares your fetish, a 0.001% chance she lives near you and a 0.000...0001% chance she wants you as a bf, unless you happen to be alpha as fuark.

even if you don't know the right answer you can bring it down to a choices between 2 or maybe 3.
it's not a game of luck: it's general knowledge. the more you live, hear news, travel, read random books and shit the higher are your chances.

/fit/ here:

there's 95% chance she's not mentally retarded
there's 95% chance she doesn't have a boyfriend or is ready to dump him
there's 95% chance she'll grow to love your fetish (women in bed want to be treated as an object and relish it - stop thinking what she might want and answer yourself what do YOU want. Then do it)
100% chance there are chicks that live near you that are dtf.

And btw:
> a 0.000...0001% chance she wants you as a bf

What the fuck does it matter what SHE wants? Why is the focus on the girl? With that mentality you'll get absolutely nowhere.

You have your own life and a girl is only there for a ride - you make the rules, you tell her what you're gonna do and you don't take shit from her. Stop thinking whether she likes you and start thinking whether you like her.

That is all.

Then you'll die alone and you will never be in a happy and stable relationship. Strong love is always based on male dominance.

Woman WANTS to be treated as an object. Her natural state is submission. This is why women love you more if you are an alpha and a natural leader.

Do not go against nature or it'll leave you nothing but misery.
