Step-by-step explanation:
I cant be 100% sure as i am not in statistics, but by definition cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research (in this case its the phone book). Researchers then select random groups (three random pages) with a simple random or systematic random sampling technique for data collection and data analysis(interviews).
so that appears to be what is happening in this scenario.
The solution 
is mathematically given as
- P(X=3)= 0.17
<h3>What is the
solution ?</h3>
Generally, the equation for the Probability of P(X=3) is mathematically given as
b)
Therefore
P(X=3)= 0.17
