A two-way table summarizes 155 practice-test takers in a peer review group. Rows show attendance pattern; columns show feedback rating. Counts: Regular attendance: Strong=6, Moderate=7, Weak=7, total=20; Occasional attendance: Strong=15, Moderate=27, Weak=30, total=72; Makeup attendance: Strong=25, Moderate=5, Weak=33, total=63; column totals: Strong=46, Moderate=39, Weak=70, grand total=155. A person from the table is selected at random. Which expression correctly computes P(Strong given Makeup attendance) from the table?
