Answer 1

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.
