A website reports that 90% of its users are from a certain country. Of the users from the country, one-half log on every day. Of the users from other countries, one-fifth log on every day. Draw a tree for this situation. Why is the tree better than the table in this case? Where are the joint probabilities found? Draw a tree for this situation and round all decimal probabilities to two decimal places as needed. Choose the correct answer below. O A. Country Every day 1/2 0.9 0.1 1/5 Not every day Not country 0.05 Country 0.18 0.9 0.1 0.45 Not country 0.02 Determine why the tree is better than the table in this case. O B. G Country 0.9 ⒸA. A tree is better because the the events described are independent. OB. A tree is better because the events given are disjoint. O C. A tree is better because joint and marginal probabilities are given, not conditional probabilities. O D. A tree is better because conditional and marginal probabilities are given.
