Why do some sets of Christmas lights work even if a few bulbs are broken while other sets will not work if even a single bulb is missing or broken?

Thank you for the opportunity to help you with your question!

Some sets are in series while others are in parallel - with their wiring. If one light goes out in a series circit, all of the lights will go out, but if they are in parallel the rest will still work.

Please let me know if you need any clarification. I'm always happy to answer your questions.
