Why so early today?

do you post this same crap everyday?

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.

supply and demand. thats all it is.

as long as there are people who respond to it, it will be posted.

>>5038325
I heard there's a huge demand for cute science threads.

you are wrong

it's 50%

either you win, or you don't

Oh man, not this shit again.

>>5038332
Your personal dislike against probability theory is irrelevant.

>>5038326
do eeeet

>>5038330

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%

did somebody say daniella titan, the queen of /sci/?

>>5038352

do you mean 'this" daniella titan?

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%.

you fucking retard chimp

>>5038407

i like you.

why don't you like me?
