Answer:
P = number of adults who have shopped at least once on the internet / number sampled adults
Step-by-step explanation:
Step 1
Let X be the number sampled adults
Let Y be the number of adults who have shopped at least once on the internet.
Let P be the probability that a randomly selected adult has shopped on the Internet.
Step 2
P = number of adults who have shopped at least once on the internet / number sampled adults
P = Y/X
An example:
If X is 1000 adults and Y is 200 adults therefore P = 200/1000 = 0.2
One can therefore infer that approximately 0.2 of the population surfs the internet at least once in a week.
