Disjoint Sets'

Two sets [math]A[/math] and [math]B[/math] are said to be disjoint if they have no element in common.
i.e.[math]A \cap B=\phi[/math]


Let [math]A=[/math][1,2,4,7,8} and [math]B=[/math]{0,3,9,12}
then [math]A\cap B=\phi[/math]

Let [math]A=[/math][a,f,e,t,y,h} and [math]B=[/math]{v,b,n,m,j,r}
then [math]A\cap B=\phi[/math]

Let [math]A=[/math][multiples of 2 which are less than 64} and [math]B=[/math]{multiples of 7 greater than 60}
then [math]A\cap B=\phi[/math]
