@kirkus Your use of Conditioned is odd, the second argument should be a condition returning True or False, now it's an integer.
Well, both of them should be such, actually. Did you mean (rr > 0 || ar > 0) \[Conditioned] (rr > 0 || ra > 0) ?

@kirma well that's a good question. I was trying to model "probability first chip defective" and "probability of second chip defective" as "rr + ra" and "ar + rr", respectively.
and then my attempt at Conditioned followed from "probability of second chip rejected given first chip rejected"

@kirkus In the case of combination of Probability and Expectation both arguments of Expectation need to result a boolean value, anyway.

ok, so if I break it down even simpler, and forget the conditional:

Probability[rr + ar,
{rr \[Distributed] BernoulliDistribution[0.01],
ra \[Distributed] BernoulliDistribution[0.01],
ar \[Distributed] BernoulliDistribution[0.01],
aa \[Distributed] BernoulliDistribution[0.97]}]

why does that generate conditions? I guess I'm trying to find an idiomatic way, if possible, to use `Probability` for those types of a priori probability problems.

Does anyone know if built in fractional calculus functionality is planned for Mathematica?

I have a notebook, which is very long. Suddenly, the equals key has become "hot": In "Input" cells, typing = anywhere in an input cell converts the cell to "WolframAlphaShort". I have several notebooks open, and in a few I've tested, = works normally. Any suggestion to help me figure out what went wrong?
The style definitions for "Input" in both types of notebooks are identical.

It feels very quiet on the SE of late. I wonder if it's the usual summer tumbleweed on top of the pandemic. I also wonder will we see a september rush this year...
I just "retired" and I'm hoping to spend a lot more time in WL over the next couple of weeks and months. Hopefully I'll finally learn a bit more Actual Maths.
And hopefully I'll finally reach 10k rep ;)
