If you are randomly choosing 8 people from an audience that contains 50\% democrats, 30\% republicans, \( 20 \% \) green party, what is the probability of choosing exactly 4 democrats, 3 republicans, 1 green party member?

Step 1
- Probability of choosing a Democrat (\(P(D)\)) = 0.50 - Probability of choosing a Republican (\(P(R)\)) = 0.30 - Probability of choosing a Green Party member (\(P(G)\)) = 0.20 Show more…

(1 point) Rework problem 27 from section 4.1 of your text involving a poll of registered voters. Assume that 40 percent of voters are Republicans, 20 percent are Democrats, and 40 percent are Independents. A poll taker asks 9 people at random for their party affiliation. Assume further that, because the city is so large, this situation can be approximated by a Bernoulli process. What is the probability that at least 7 of those polled are Democrat voters?

On December 17, 2020, Gallup polling found that 31% of Americans identified as Democrats, 25% identified as Republican, and 41% as Independent. Suppose you randomly sample seven Americans. (a) What is the probability that exactly three Democrats were chosen? (b) What is the probability that you chose at least five Independents? (c) What is the probability that you chose more than one Republican?

If we choose 7 people at random from a population that has 60% Democrats, and let X = the number of Democrats chosen (out of the 7), then the probability table for X is as follows: X 0 1 2 3 4 5 6 7 probability 0.0016 0.0172 0.0774 0.1935 0.2903 0.2613 0.1306 0.028 A) What is the probability that less than 3 are Democrats? B) What is the probability that more than 3 are Democrats? C) What is the probability that at least 5 are Democrats?
