Question

If A = {4, 5, 6, 7, 8}, then find n(A)

Answer 1

if A= {4, 5, 6, 7, 8}

n(A)= the number of elements in the set A

so n(A) = 5, as their are 5 elements in the set

Answer 2

n means the no. of letters or no.s in it

for eg B={1 2 3 4 5 6 }

so in here there are totally 6 no.s therefore n(B) = 6
