There will be 30% of houses without fibre optic internet connectivity or high-definition television.
Groups of components with definite definitions are called sets. A curly bracket serves as a symbol for the number of objects in a finite set.
To choose a subset from a set and draw a conclusion using statistical analysis, use random sampling.
In one town, 20% of homes have both fiber-optic internet connectivity and at least one high-definition television, whereas 40% of homes have one or the other.
The percentage of residences without fibre optic internet connectivity or high-definition television is as follows:
P = 100% - [60% + 30% - 20%]
P = 100% - (90% - 20%)
P = 100% - 70%
P = 30%
30% of houses will not have fibre optic internet connectivity or high-definition television.

Answer:
Certificate Revocation List
Explanation:
According to my research on different professional requirements, I can say that based on the information provided within the question the term being describe in the question is called a Certificate Revocation List (CRL). This is (like defined in the question) a list of digital certificates that have been revoked by the issuing Certificate Authority, before they actually expire making them obsolete and letting anyone interested know that they should no longer be trusted. This list is usually looked at when someone runs across a signature and want to know if that person actually holds that certain certificate proving that they have the knowledge that is required.

Answer:
c. $31,888
Explanation:
The formula for calculating the present value is as below
Pv = FV x { 1/ (1+ r)^n }
Pv = $40,000 x { 1/ (1 +0.12)^2
Pv =$40,000 x (1/1.2544)
Pv =$40,000 x 0.7971938
Pv =$31,887.50
