Any one of the inequalities (written with red color) should be sufficient for us to find the required sample space but it leads to the wrong answer (also clearly using only one of those inequalities as a sufficient condition leads to 2 answers) thus the condition on 3 positive scales which I found must be wrong but I'm unable to find my mistake in it please help
