hello,(adsbygoogle = window.adsbygoogle || []).push({});

I really dont know how to proceed here, since I dont know very much about sets/family.

I want to prove that if Ð is a family of pairwise disjoint sets, and Ŧ is a subset of Ð, prove that Ŧ is also a family of pairwise disjoint sets.

Thanks in advance math gurus
