Answer:
1. 0.3
2. Relative frequency
Step-by-step explanation:
We would be calculating for p(A) which is the probability of A. With A being that public buildings would be found to be insulated with same materials that causes same issues
n = sample space of public buildings = 10
F = frequency = 3
P(A) = 3/10 = 0.3
Therefore 0.3 is the approximate probability of another building having same issues
Question 2 says we should find method used to assign probability
The method used is relative frequency method and it is determined by:
P(A) = frequency(f)/total number of data values(n).
