Help
Hey, I'm entering a comp on the radio, and can't remember any old probability stuff. What I have to do is 'guess' a 3 digit number. I already know that 1 is the middle digit and it has an 8 somewhere in it, and I can cross some options off (other people tried and failed to guess it)
Could you please help me come up with the most likely option/s?
The possible numbers are:
018
118
218
418
718
818
918
810
811
812
813
814
819

If those are your only possibilities, then you have a 1 in 13 chances to get the numbers...
But what is the system of this game exactly?

Yea, I got that far haha.
Every hour someone can call up and say a 3 digit number that they think it is, so I've been checking off wrong numbers, but it's only a certain amount of time before someone gets it...
The winner gets $10,000! I know they broadcast on the frequency 91.8 in a different region, so that'll be my first guess, but I was just wondering if there was a mathematical way of working out the most probable number

You'll have to take the risk...
Either you make THE guess, or you make one whic will make the next guess easier...
Do you get something for guessing 1 number of the 3 digits?
There was one similar game here in my country some years ago, but with a smaller sum.
