A 5-column table has 4 rows. The first column has entries A, B, C, Total. The second column is labeled X with entries 10, 110, 6

0, 180. The third column is labeled Y with entries 80, 44, 59, 183. The fourth column is labeled Z with entries 61, 126, 110, 297. The fifth column is labeled Total with entries 151, 280, 229, 660. Which statement is true about whether Z and B are independent events? Z and B are independent events because P(Z∣B) = P(Z). Z and B are independent events because P(Z∣B) = P(B). Z and B are not independent events because P(Z∣B) ≠ P(Z). Z and B are not independent events because P(Z∣B) ≠ P(B).
