How do I know when to use の with が in a "good/bad at" sentence?


In all sentences that describe someone being good or bad at something, as well
as liking/disliking doing something, the particle が is used. I know for a fact
that you use が for like/dislike.

In some sentences, the particles のが are there. i.e: "I don't really like doing
the laundry"

> 私はせんたくをするのが好きじゃないです。

Why is there a のが instead of just が？




のがis used with a verb when the focus is shifted to the verb despite the
sentence having a subject defined by は. It was similar to usage to のは, but
with different focus. Like in the example the subject is watasi, but the focus
is on sentaku suru.
