Answer 1

Answer:

Set A has 3 elements.

Set B = {3, 4, 5} i.e. 3 elements.

Number of elements in (A × B) = n(A × B)

⇒ n(A) × n(B)

⇒ 3 × 3

⇒ 9 elements

• Sets are the well defined collection of elements or objects.
• The two forms of representation of sets - Roaster form and Set builder form.
• Singleton set includes just one element.
• Equal sets are two sets A and B where every element of set A is also an element of set B.
• Equivalent sets are two sets A and B where the number of sets of A is equal to the number of sets of B.
• A set which contains finite elements is a finite set.
• A set which contains infinite elements is an infinite set.
• Element which contains no element is an empty set.
