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.

Oh look, it's THIS thread again.

How are the odds of getting a correct answer 1/3? There's 4 choices and one correct. It should be 1/4. Is this a troll thread?

if i flip a coin with 50% chance of heads or tail 10.000 times i have 50% chance to get all heads all the time
0.5+0.5+0.5.......0.5/10.000=0.5
yup thats how probability works

[Anonymous No.5716368]

I'd like to understand why 1 correct answer and 3 incorrect answers gives you 1/3 and therefore 33.34% probability of guessing the correct answer. By this logic, if you flip a coin, the likelihood is 1/1 heads, therefore 100% chance. How can this be?

Perhaps I am just getting trolled.
