For each set, given below, state whether it is finite set, infinite set or the null set:
Set of mountains in the world.
Step: Check whether the given set is finite set, infinite set or the null set
Given: Set of mountains in the world
Since the mountains in the world are uncountable.
And we know that a set is said to be an infinite set, if it has an uncountable number of elements in it.
Hence, the given set is an infinite set.
