Answer»

Hello! ! !


⚫Hey my dear friend here is your answer⚫ ______________________

Given,

A = { x|x € N, 1 < x < or = 10 }

since x is greaterthan 1 and x is less than or equal to 10 means the vale of x LIES in between 2 and 10.

ie. A = { 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 }

therefore,

n (A) = 9
