    2 included in 1 and not the other so nothing in common.

    An arbitrary element \(\phi\) will always fulfil the condition \(\phi <2\) in set \((1,2)\). An arbitrary element \(\psi\) will always fulfil the condition \(\psi \ge 2 \) in set \([2,3)\). So, \(\rm \psi \ge 2>\phi\). Therefore, there is no common element.

    The interval (1,2) can be interpreted as a set containing numbers between and not including 1 and 2.

    In this case, we have \(\phi \) instead.\[(1,2) = \{\phi \in \mathbb R |1<\phi <2\}\]Doesn't make a lot of difference either...
