Any interval of positive length is uncountable | Proof of (0,1) is uncountable | Uncountable Set

In this video,I discussed about cardinality of a set and cardinal number of a set.We will use cardinal number to find a set is countable or not. I also explained this with several important examples. In next video,i will discuss about countable and uncountable of a set.
