A bank is considering extending credit to a new customer and is interested in the probability that the client will default on the loan. Based on data that the bank has accumulated over many years of business, there is a 5% chance that a customer who has overdrawn an account will default on the loan, whereas there is only a 0.5% chance that a customer who has never overdrawn an account will default on the loan. Unfortunately, the bank does not know for sure what type of risk the new customer will turn out to be. Based on background checks and credit reports, the bank believes that there is a 30% chance that the new customer will overdraw the account. Determine the probability that the customer will default on the loan if credit is extended.
