Doubt in Rice's Theorem
I have a doubt while understanding step 2 in proof of Rice's Theorem- According to my understanding,proof of Rice's theorem as follows ( Please suggest If something is wrong in my understanding) P is a property of languages of TM which is non-trivial ... Same problem as ATM). Can M' take decision in finite time. Please give me some insights to I can understand this point.

Turing Machine Rice's Theorem
L = {M|M is a TM that accepts all even numbers} For the above language i can have Tyes machine which has all even numbers.And Tno as machine whose language is empty.So i can say it is undecidable. But to show it is Not RE. What ... am assuming here that the property of the language as "Only all even numbers",i guess the same has been given in the question.

Rice's Theorem
Example# 3 from Part-1 Rice's Theorem from https://gatecse.in/rices-theorem/ states as follows (3) L(M) is recognized by a TM having even number of states Sol: This is a trivial property. This set equals the set of recursively enumerable languages. According to ... then? Can someone give me an example for which TYES and TNO cannot be found and let me know if my approach is correct ?

Rice's Theorem
I am unable to understand when to apply Rice's theorem and when to not. How L2 is decidable.
