Question

Ifa set is defined as A= {x: x is a factor of 12}, then find n(A). Fast plz

Answer 1

Step-by-step explanation:

A= {x: x is a factor of 12}

in tabular method,

A = {1, 2, 3, 4, 6, 12} ,where x belongs to N

hence, n(A)=6

if x belongs to W , then

A = {0, 1, 2, 3, 4, 6, 12}

and n(A)= 7

hope it'll help you.
