Question

Recall your consultancy work for Drovandi Marketing and Networks (DMN) from your last PST.
In the final phase of your current project, MXB101, you are required to delve into the minds of
customers. DMN has taken a large survey of customers buying a particular product. From this
survey, they know that:
• 25% of customers are under 25.
• 60% of customers are between 25 and 50.
• 15% of customers are over 50.
DMN estimates that 20% of the population in the local area have bought this product. DMN has
surveyed locals who haven’t purchased the product and estimates that:
• 70% of non-customers are under 25.
• 10% of non-customers are between 25 and 50.
• 20% of non-customers are over 50.
What is the probability that a person under 25 will buy this product using laws of Probability or Bayes or Both?

My tutor says that I have to use the Laws of Probability and Bayes. I am really struggling with this problem. Can someone help me to solve it as soon as possible?
