When users type URLs into the browser (i.e. in order to visit a web page), of the 6 possible permutations, what is the percent of the time that each permutation is entered?
The reason for wanting to know this is because it can be (surprisingly) challenging to get all 6 permutations working (depending on things like the domain name registrar and hosting provider used) so sometimes a site will not be set up in a way such that all 6 permutations work. Having knowledge of the percent of the time each permutation is typed would help quantify the extent of inconvenience to users when one or more of the 6 permutations don't work.
A random example would be in the case a site had 5 permutations working, but not https://example.com; such statistics would allow for estimates of the approximate percent of users who attempt to type in a URL who will be inconvenienced.
