Using it's concept, it is found that the probability that the special ball is chosen is given by:
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The total number of outcomes is given by the combination of k balls from the set of n balls, given by:
One ball is special, hence the probability the special ball is chosen is given by:

Answer:
4686825
Step-by-step explanation:
Given : Researchers plan to use a simple random sample of 9 subjects selected from a pool of 27 available subjects.
To Find : How many different simple random samples are possible?
Solution:
Total subjects = 27
No. of subjects should be in sample = 9
So, to find How many different simple random samples are possible?
So, we will use combination
n = 27
r = 9
Substitute the values
Hence 4686825 different simple random samples are possible
Answer:
C Population
Step-by-step explanation:
Population
The above case is an example of population survey. Here a set of 56 surveys have been performed with set of 56 students. The survey is conducted on a large scale. In statistics a population is set of similar items or events which is of the interest for some event or experiment. Since, the above experiment fits the definition of the Population, it is example of population survey.
