The table displays the distribution of blood types A, B, AB, and O to the presence of the Rh factor that is either present (Pos.) or absent (Neg.).

A 6-column table has 3 rows. The first column has entries negative, positive, total. The second column is labeled A with entries .07, .33, .40. The third column is labeled B with entries .02, .09, .11. The fourth column is labeled AB with entries .01, .03, .04. The fifth column is labeled O with entries .08, .37, .45. The sixth column is labeled Total with entries .18, .82, 1.0.

Use the information in the two-way table to complete the statement.

percent.

P(Pos | O) = 0.37 / 0.45 = 0.8222... ≈ 82.22% (≈ 82.2%).

There is a greater probability for a person to have a positive Rh factor given type O blood (≈82.2%) than to have a negative Rh factor given type O blood (0.08/0.45 ≈ 17.78%).
