Answer:
n(C) = 2
Step-by-step explanation:
A set is given as C = {3, 5}. That means set C is having tow elements.
n(C) is referring the number of elements of the set C.
n(C) is also known as cardinality of the set.
In the given set number of elements are two so cardinality of the set n(C) is two.
Therefore, n(C) = 2 will be the answer.
