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 15% are under the age of 50 and conduct their banking online. Make a probability table. Why is a table better than a tree here? Complete the probability table below. Online Banking Yes No Total Under 50 Age 50 or Older Total (Type integers or decimals. Do not round.) Why is a table better than a tree here? OA. 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. OB. A tree is constructed using conditional probabilities, but this problem gives joint and marginal probabilities, which is more suited to a table. OC. A tree is constructed using joint and marginal probabilities, but this problem gives conditional probabilities, which is more suited to a table. probability model with more than one variable, while a table can be used to show two variables.

Choose an American adult at random.  The probability that you choose a woman is 0.52.  The probability that the person you choose has never married is 0.24.  DRAW A TREE DIAGRAM to find the probability that the person you choose is a woman who has been married.

In the United States, voters who are neither Democrat nor Republican are called Independent. It is believed that 9% of voters are Independent. A survey asked 27 people to identify themselves as Democrat, Republican, or Independent. A. What is the probability that none of the people are Independent? Probability = B. What is the probability that fewer than 5 are Independent? Probability = C. What is the probability that more than 3 people are Independent? Probability =

You play two games against the same opponent. The probability you win thefirst game is 0.4. If you win the first game, the probability you also win the second is 0.2.If you lose the first game, the probability that you win the second is 0.3. A tie is not anoption.a. Are the two games independent? Explain.b. What’s the probability you lose both games?c. What’s the probability you win both games?d. Let random variable X be the number of games you win. Find the probabilitymodel for X.
