★$<u> <b> Sets </u> </b>$★

Given that ,

★ n ( X) = 17

★ n ( Y ) = 23

★ n ( X U Y ) = 38

→ n ( X ∩ Y ) = ?

$<u> using the formula :- </u>$

→ n ( X U Y ) = n ( X ) + n ( Y ) - n ( X ∩ Y )

→ 38 = 17 + 23 - n ( X ∩ Y )

→ 38 = 40 - n ( X ∩ Y)

$<b> •°• n ( X ∩ Y ) = 2</b>$


$<b> Note :- </b>$


→ ∩ means the Intersection i,e common elements of two sets!

→ U means the Union i,e addition of all the elements of two sets !
