Hi everyone,

I am currently studying existential quantifiers and although I understand the concept of existential quantifiers, I find it difficult to apply the concept to MBF questions. I've only done a couple of MBF questions with existential quantifiers, but was wondering whether you need to use existential quantifiers for each MBF question? Also, what types of logical reasoning questions require us to use existential quantifiers?

If possible, can someone please reference some questions that require us to utilize existential quantifiers? I would greatly appreciate it! Thanks in advance :).
