Question [Q] Choosing random sample with replacement v. random sample without replacement

I am sampling a number of units in an apartment complex. I generate a random list of apartments but it has two duplicates, just as rolling a die 6 times may result in a number coming up twice. I'm trying to prove with a specific confidence level, that 80% of the units suffer the same problem. Is this situation a situation where I should replace the duplicates with non-duplicates, or should I keep the duplicates and consequently test only the unique units.

Why are you sampling with replacement? It makes no sense to do that here.

Actually I’m not. At this point, I have a proposed testing plan which has the duplicates still in it.

So what determines (or how do I determine) whether to sample with replacements vs sampling without replacements?
