Answer #1

Democrats voters | 39.1% |

Republicans voters | 60.9% |

Democrats voted | 30.8% |

Republicans voted | 39.6% |

a.

If a citizen who voted in the last election is randomly
selected, what is the probability **that they are a
Republican?**

39.6% - 30.8% = 8.8%

probability that they are a Republican = 0.088

b.

If a citizen who is a **Democrat** is randomly
selected, what is the probability that they did not vote in the
last election?

39.1% + 30.8% = 69.9%

probability that **Democrat** did not vote in the
last election = 0.699

In a given county, records show that of the registered voters,
50% are Democrats, 35% are Republicans, and 15% are
Independents. In an election, 80% of the Democrats, 40% of the
Republicans, and 90% of the Independents voted in favor of a parks
and recreation bond proposal. If a registered voter chosen at
random is found to have voted in favor of the bond, what is the
probability that the voter is a Republican?
