If one woman has one [pair of obligatory bird-offerings], and another woman has two [such pairs], and another woman has three [such pairs], and another woman has ten [such pairs], and another woman has one hundred [such pairs] —- [if the Kohen] made all of them above [the Red Line], half [of the mingled offerings] are valid and half [of them] are invalid; [if he made] all of them below [the Red Line], half [of the mingled offerings] are valid and half [of them] are invalid. [If he made] half of them above [the Red Line] and half of them below [the Red Line], [the number of pairs in] the largest group is valid.  This is the rule: Every situation in which you can divide the pairs [in a way] that one woman’s [bird-offerings] will not be both above [the Red Line] and below [the Red Line], [then] half [of the mingled offerings] are valid and half [of them] are invalid. [And] any situation in which you cannot divide the pairs other than [in a way] that one woman’s [bird-offerings] will be both above [the Red Line] and below [the Red Line], [then the number of pairs in] the largest group is valid.
