List number of family members with counters

Question

I learnt that to say:

I have two younger brothers and one younger sister?

in Japanese, I can use:

弟と妹が二人います。 (Otōto to imōto ga futari imasu).

The grammar structure is the following:

Noun + が + counter (for people) + います

But now I'm having trouble with this sentence:

I have two younger brothers and two younger sisters? (Note: both nouns are plural).

Will the following sentence be correct:

弟が二人と妹が二人います。 (Otōto ga futari to imōto ga futari imasu).

Answer 1

If you want the structure:

Noun + が + counter (for people) + います

You can combine two clauses like this (have you already learned this before?)

弟が二人いて、妹が二人います。

It's also possible to phrase it like this:

counter (for people) + の + Noun + が + います

So that it becomes:

二人の弟と二人の妹がいます。
