Need some help on some of these problems. Thanks in advanced.(adsbygoogle = window.adsbygoogle || []).push({});

Ø

E = is an element of...

1. Ø E {{Ø}1,2}

False? I'm a little confused. Is Ø on the left side a set? So, can it be equivalently written as {Ø}? If so, then it can't be an element of something, since it's actually a set, or in this case a subset.

2. {2} E {1,2,3}

Confused again here with the 2 being in braces, does it mean it's a set and therefore can't be an element of something? False?

3. Ø = {Ø}

No idea here. I'm guessing true.

Any help is appreciated. Thanks again.
