Question

**In a large town, the size of the population is 1200. 744
of the citizens have a healthy diet.** (You may assume that
all sampling is done WITH REPLACEMENT)

1. What is the proportion of the population that has a healthy diet? (express the proportion as a decimal)

2. If **one** citizen is randomly selected from the
population, what is the probability that the citizen has a healthy
diet? (express the probability as a decimal)

3. If **one** citizen is randomly selected from the
population, what is the probability that the citizen does
*not* have a healthy diet? (express the probability as a
decimal)

4. If **4** citizens are randomly selected from the
population, what is the probability that all of them have a healthy
diet? (you can round to 5 or more decimal
places)

5. If **4** citizens are randomly selected from the
population, what is the probability that exactly 2 have a healthy
diet? (you can round to 5 or more decimal
places)

6. If **4** citizens are randomly selected from the
population, what is the probability that at least 2 have a healthy
diet? (you can round to 5 or more decimal
places)
