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.

Not enough information and anyone who says otherwise is trolling.

Math is just a social construction. It's only "true" because our Western culture says it's true. Aliens probably have math that says 1+1=4. Math is not true universally. So, the answers in this thread are correct from a certain point of view.

x = 1 + 0.5x

0.5x = 1

x = 1/0.5 = 2

Math isn't numbers on paper. Math is interactions between quantities. If alien math says 1+1=4 it's only because the quantity represented by "4" is equal to double the quantity represented by "1". In any universe •+•=••…
