Symbol r_A

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

What this part means

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

Its job in the formula

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

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…
