What does joint mean?

[W_Heisenberg]

There are many joint things around, what are they?

e.g. joint probability

Joint would just mean that there are multiple variables under consideration. In particular, for joint probability, see https://en.wikipedia.org/wiki/Joint_probability_distribution

There is no such thing called ``joint probability".

There is no such thing called ``joint probability".

care to elaborate ?

 

[pangpangfish]

Probability is defined for a set, which can be, say, intersection of two sets. There is no such thing called joint probability. You can have joint probability density or joint cumulative distribution function. But you never say ``joint probability".

so you were just being pedantic...

Aww, was I?

but finally, I think joint means things happen simultaneously
