Sally is interested in finding out if the political party affiliation of Americans who are registered to vote is related to whether or not they believe in ghosts. Suppose she finds that, among all Americans who are registered to vote, 29.5% are registered Democrats and 24.6% are registered Republicans. Among all registered American voters, the percent of people who are Democrat and who believe in ghosts is 7.8%, the percent of people who are Republicans and who believe in ghosts is 6.5%, and the percent of people who affiliate with other political parties and who believe in ghosts is 12.1%. Label each branch of the tree diagram with the correct probability value.

Sally is interested in finding out if the political party affiliation of Americans who are registered to vote is related to whether or
not they believe in ghosts. Suppose she finds that, among all Americans who are registered to vote, 29.5% are registered
Democrats and 24.6% are registered Republicans. Among all registered American voters, the percent of people who are
Democrat and who believe in ghosts is 7.8%, the percent of people who are Republicans and who believe in ghosts is 6.5%,
and the percent of people who affiliate with other political parties and who believe in ghosts is 12.1%.
Label each branch of the tree diagram with the correct probability value.

Expert Solution
Step 1

Given:

  • Probability of democrat party is, P(D)=29.5%=0.295.
  • Probability of republican party is, P(R)=24.6%=0.246.
  • Probability of democrats believe in ghost is, P(BD)=7.8%=0.078.
  • Probability of republicans believe in ghost is, P(BR)=6.5%=0.065.
  • Probability of other parties believe in ghost is, P(BO)=12.1%=0.121.

The objective is to label a tree diagram with all probability values.
