I’m surprised! I always thought if they had any overlap, they were exclusive.

Nope, definitely not disjoint. The overlap proves it.

Wait, I thought mutually exclusive meant they couldn't overlap at all?

Totally agree, they can happen at the same time!

They’re not mutually exclusive since P(A&B) is not zero.

I believe the answer is no, since P(A&B) is given as .10, but I need to double-check my notes on this.

I feel like I might be mixing up the definitions. If they can happen at the same time, then they shouldn't be disjoint, right?

I remember a similar question where we had to check if the intersection was zero to determine mutual exclusivity.

I think A and B are not mutually exclusive because P(A&B) is not zero, but I'm not entirely sure.

I'm pretty confident I can solve this. I just need to remember the definition of mutual exclusivity and compare the given probabilities.

Okay, I've got this. If A and B are mutually exclusive, then P(A&B) should be 0. Since P(A&B) = 0.10, that means A and B are not mutually exclusive.

I'm a bit confused by the given probabilities. How do I use them to determine if A and B are mutually exclusive?

Hmm, this looks like a classic probability problem. Let me think this through step-by-step.

Hmm, I'm not sure how to approach this. Maybe I should review the formulas for mutually exclusive events before answering.

Hmm, I'm a bit unsure about the specifics of Cisco ACI and spanning tree policies. I'll need to review my notes carefully to make sure I understand the right steps.

Wait, what if A and B are like cats and dogs? They're always at each other's throats, so they must be mutually exclusive! *laughs*

Hold on, I've got this. The fact that P(A&B) = 0.10 means they are not mutually exclusive. The answer has to be B, no.

No way, A and B can't be mutually exclusive if their individual probabilities add up to more than 1. This must be a trick question!

I think A and B are mutually exclusive since the probability of their intersection is only 0.10.
