Consider the two-way table below.

A 4-column table has 3 rows. The first column has entries A, B, total. The second column is labeled C with entries 15, 9, 24. The third column is labeled D with entries 21, 25, 46. The fourth column is labeled Total with entries 36, 34, 70.

Find P (B|C).

P (B|C) = StartFraction 9 Over 34 EndFraction = 0.26

P (B|C) = StartFraction 9 Over 24 EndFraction = 0.38

P (B|C) = StartFraction 9 Over 70 EndFraction = 0.13

P (B|C) = StartFraction 9 Over 58 EndFraction = 0.16
