E= {1, 2, 3}
f = {101, 102, 103, 104}
e ∩ f =

{ }
{1, 2, 3}
{101, 102, 102, 103, 104}
{1, 2, 3, 101, 102, 103, 104}

E ∩ F = {}

Step-by-step explanation:

Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,

Given

E = {1, 2, 3}

F = {101, 102, 103, 104}

We have to find the intersection of both sets as indicated

So,

E ∩F =  {1, 2, 3} ∩ {101, 102, 103, 104}

E ∩ F = {}

As there are no common elements in both sets the intersection will be an empty set
