Proof: Let A be an event. Then ∅ ⊂ A help by elucidating

OpenStudy (nincompoop):

Let A an arbitrary event, and since an empty set indicate no points, it is sound to point out that every point belonging to ∅ belongs to A

OpenStudy (anonymous):

the empty set is a subset of every set vacuously so as \(A\subset B\iff x\in A\implies x\in B\)

OpenStudy (nincompoop):

that's the kind of notation I am looking for! thank you @satellite73

Miracrown (miracrown):

that is basically saying that the empty set is a subset of the event A The empty set is a subset of all sets

OpenStudy (anonymous):

you know how to check it right? i mean the \(\LaTeX\)

OpenStudy (nincompoop):

I am a TEX newbie

OpenStudy (anonymous):

\[A\subset B\iff\forall x, x\in A\implies x\in B\] would be more precise

OpenStudy (anonymous):

right click and check what you need

Miracrown (miracrown):

Yes that is the definition of a subset. Every element that is in A is also in B ^

OpenStudy (nincompoop):

thanks also, @Miracrown

Miracrown (miracrown):

i did nothing tho

OpenStudy (nincompoop):

you participated LOL that's good enough

Miracrown (miracrown):

sureeee.... I was under the impression that the empty set was defined to be a subset of all sets. I am not really sure how to prove it A set with no elements is essentially a subset of any set because no element is also part of any other set

OpenStudy (anonymous):

it is because of the definition that starts with IF \(x\in A\)

Miracrown (miracrown):

Ok, since x is not an element of the empty set, then that is by default false, and any implication that starts with F is by default true

OpenStudy (nincompoop):

spanks!
