Theoretical application of set in Covid 19 for child, young and adult. By giving appropriate example. (specified place like:Kathmandu, Pokhara, Birgunj, Janakpur,etc)

One theoretical application of set theory in the context of COVID-19 could be to analyze the age distribution of the virus among different populations in different regions of Nepal, such as Kathmandu, Pokhara, Birgunj, Janakpur, etc.

For example, we can define three sets: one for children (ages 0-12), one for young people (ages...
