Question

Suppose A = {2,5,7,9,13, 25, 26).
(a) Find n(A).
n(A) =
(b) T/F: 7. A​

Answer 1

a) n (A) = 7

Explanation:

Here, set A = {2,5,7,9,13, 25, 26)

Noe, for any set A,

n (A) is defined as he total number of elements in the set A.

or, n(A) = CARNALITY OF SET A

Here,the number of elements in set A = 7

⇒ n (A) = 7
