Suppose you have a dataset of customer information, including their age, income, and whether or not they have made a purchase in the last 30 days. You want to build a llama model to predict the probability of a customer making a purchase in the next 30 days based on their age and income.

Using your llama model, what is the probability that a 35-year-old customer with an income of $50,000 will make a purchase in the next 30 days?
