Injective, surjective and bijective

Prof. Dr. Christian Bär

Two random sets $X$ and $Y$ and a random map $f$ from $X$ to $Y$ are generated. Check whether or not this map is injective, surjective or bijective, respectively.

After hitting "Update" you will see the result to check your considerations. At the same time, a new exercise is generated.
