Homework: Homework 6 core: 0 of 6 pts Section 12.6 Exercise 18 A national survey indicated that 50% of adults conduct their banking online. It also found that 40% are under the age of 50, and that 10% are under the age of 50 and conduct 2016 (5 complete) HW Score: 50.1 Make a probability table. Why is a table better than a tree here?

Why is a table better than a tree here? A. A tree cannot be used to express a probability model with more than one variable, while a table can be used to show two variables B. A tree is constructed using conditional probabilities, but this problem gives joint and marginal probabilities, which is more suited to a table C. A tree cannot be used to express a probability model with a single variable, while a table can be used to show single variable models D. A tree is constructed using joint and marginal probabilities, but this problem gives conditional probabilities, which is more suited to a table Click to select your answer and then click Check Answer All parts showing Clear All Fina

Explanation / Answer

here option B is correct as a tree is constructed using conditional probabilities, but this problem gives joint and marginal probabilities, which is more suited to table.

In short, tree analysis is more suited one variable and then associated conditional probability. But contingency table is good for intersection between two variables.
