${ \large{ \sf { \underline{Given-}}}}$

• Set of B = { }

${\large{\underline{\sf{To \: Find -}}}}$

• n(B) = ?..

${\large{\underline{\sf{Answer -}}}}$

n(B) = 1

Here Set of B contains pi (no elements) , So it has 1 element. So, number of elements in B n(B) = 1

${ \therefore{ \underline { \sf{n(B) = 1}}}} \:$
