Answer

Explanation:

Step1: Recall independence concept

If two variables are independent, the joint - probability is the product of the marginal probabilities. For independence, we would expect (R) to be close to the product of the marginal probabilities of the corresponding row and column. In the absence of association (independence), (R) should be close to the value we would get from the overall proportions. Since the total for row (D) is (1.0) and the total for column (A) is (U), if independent, (R) should be close to the proportion of (A) in the overall distribution. But a value far from what we would expect under independence indicates an association. The value of (0.79) is very different from what we would expect if the variables were independent (as the values in row (D) are distributed in a certain way and (0.79) would disrupt the expected pattern if there was no association).

Answer:

(0.79)
