eli5 : Mutually Exclusive

988 views

I’m sorry if this seems dumb. I tend to take things literally and “mutual” and “exclusive” seem to be antonyms but mutually exclusive is a term used a lot and it confuses the crap out of me. I’m a native English speaker also.

Does it mean that the two things CAN exist together? I feel like my brain does gymnastics trying to understand the term; I’m not a dumb person but this term just totally eludes me!

Please don’t attack me, just trying to not feel stupid.

If you draw 2 parallel lines they don’t intersect. That’s what parallel means.
If you draw perpendicular lines, they intersect at a 90 degree angle. That’s what perpendicular means.
You cannot draw two lines that are both parallel and perpendicular. They either intersect or they don’t. The options are mutually exclusive.

Now lines that are NOT parallel have to intersect. Intersecting lines can be perpendicular, but they can also intersect at a different angle.
Intersecting lines are perpendicular lines are not mutually exclusive.
All perpendicular lines intersect, but not all intersecting lines are perpendicular.

In logic or coding it is expresses as xor.
