Symbol r_B

Pmiss=(1−rA)(1−rB)P_{miss} = (1-r_A)(1-r_B)
rBr_B

What this part means

the recall.

Its job in the formula

rBr_B is one of the signed contributions combined to compute the quantity on the left.

Where the article explains it

Say check A independently has recall rAr_A against a real defect — the fraction of the time it would catch that class of problem if it ran — and check B has recall rBr_B .

The passage around this formula

Say check A independently has recall rAr_A against a real defect — the fraction of the time it would catch that class of problem if it ran — and check B has recall rBr_B . If the two checks fail for unrelated reasons, the chance a defect slips past both is the product of the chances it slips past each: Pmiss=(1−rA)(1−rB)P_{miss} = (1-r_A)(1-r_B). which is smaller than either (1-rAr_A) or (1-rBr_B) alone: real, additive protection. But if the two checks share a failure mode — most…
