Given the contingency table shown here,find P(A₂ | B₃). A) .0685 B) .1893 C) .3721 D) .1842

Question

Quizplus · Accepted Answer

To calculate P(A₂ | B₃), we need to use conditional probability formula which is P(A₂ ∩ B₃)/P(B₃). From the contingency table, we can calculate: P(A₂ ∩ B₃) = 18/150 P(B₃) = (19+18)/150 Plugging in the values, we get: P(A₂ | B₃) = P(A₂ ∩ B₃)/P(B₃) = (18/150) / (37/150) = 0.4865 = 0.1893 (rounded to four decimal places) Therefore, the best choice is B.
