EXPLANATIONS;
Here, we want to get the probability of A, given B; where A refers to the event that the person surveyed is under 40, and B is the event that he or she gets the news by reading news paper
According to Bayes' theorem, we have the formula to use as;
Since the total is the same, we can work only with the numbers
So, firstly, we need the number of people that gets the news by reading news papers; we have this as 28
Now, we need the number of people who are under 40 and also gets their news by reading papers
We have this as 4
So, we have the probability as;
We have this as approximately 14%
