Rules:

The teacher chose a number from 1 to 10.

There is a total of 10 students in my class

Each one has to say a number starting from the front

You cant repeat numbers.

The objective is to guess the teachers number.

Problem: The discussion began when one of my classmates said that because he was in the back he had a higher chance of choosing the teacher's number, because if the people on the front missed the number he would have a probability of 1/7 instead of the 1/10 that the first student had, at that point my class splited in two sides:

1st Side: they said that every player had the same chance no matter the position(first, last,etc) because you have to take on account the odds from the other players .

2dn Side: they said that not all players have the same probability, and the player in the front had a smaller chance of getting the teacher's number and the people in the back had a bigger chance.

Question:

Wich side is right? and why?

PD: Sorry if my English is bad, i used a little bit of google translate and my own knowledge so if you dont understand something in the post feel free to tell me and i will try to correct it.
