Forums - General - Stupid maths question that's been bugging me all day.

No idea why this question came to mind, but it's here and won't go away.

If you enter a competition where there are 1million entries and there can be 18 possible winners. What is the probablity that you will be 1 of the winners?

For some reason, I am convinced the answer is 1 in 18 not 1 or 18 in a million.

Anyone know the right answer?

18 in a million, number of possible wins divided by total contestants.



...

For some reason, I'm seeing it as a trick question where the actual answer is 1 in 18, can't explain it.

Sometimes you just have questions where you can't help but second guess yourself.  I lived in a couple different english speaking countries so sometimes I'll keep second guessing myself for spelling something like Crayon or tire.

Okay, I'll believe you guys. Thanks!

just imagine you had 10 balls numbered 1 to 10. What are the odds of getting a number 7?



No, it's not 1 in 18. Just like if there was 1million entries and one winner, that wouldn't mean you have a 1 in 1 chance of winning.



I think I figured out my thought process.

There are 18 possible winners, you only need to win once to be a part of that 18 so, in order to be a part of the winning 18 you just need to take up 1 spot ergo 1 in 18...why the hell did I think that?
