Which of the following are subsets of F = {drama, comedy, action, horror}? G = {drama, comedy} and H = {documentary} J = {drama, comedy, horror} and K = { } M = {drama, comedy, action, documentary} and N = { } R = {drama, comedy, action} and S = {documentary}

@midnight97

Midnight97:

I am thinking how to explain it

Phantomdex:

That's alright, take your time!

Midnight97:

I only got an example

Phantomdex:

Oh? Well then give it here I suppose ^^

Midnight97:

Midnight97:

The set is 1,2,3,4,5

Phantomdex:

Right that makes sense I think

Midnight97:

G = {1,2,3,4,5} The subset is 1,2,3 A= {1,2,3} A is subset because 1,2,3 are numbers from the set

Phantomdex:

So, the answer is a then?

Midnight97:

It is part of the example I am still thinking how to explain

Phantomdex:

Oh alright!

Midnight97:

But I know the first one isn't subsets of F

Phantomdex:

Oh alright, so a is out, at least we've narrowed it down :>

Midnight97:

I know the answer but I cannot give direct answers

Midnight97:

M = {drama, comedy, action, documentary} and N = { } isn't one as well

Phantomdex:

So it's down to b and d...

Phantomdex:

I feel like B makes the most sense since it has three of the subsets?

Midnight97:

Well mark off R = {drama, comedy, action} and S = {documentary}

Phantomdex:

Ah I see, thank you midnight, always a great help!

Phantomdex:
