Answer:
Bijective
Given:
be two sets, each with a finite number of elements. Prove that
bijection.
Hint:
Bijection should fulfil the surjective injective condition.
Solution:
are two non-empty sets.
Let be a function from
to
.
It is given that there is injective map from to
.
That means is one-one.
It also given that there is injective map from to
.
That means is onto
is bijective.
