Ans.  Regression
                     c.  A marketing company wants to segment its customer base into distinct groups based on purchasing behaviour for
                       targeted marketing campaigns. They have a dataset containing information such as purchase history, frequency of
                       purchases, and amount spent.
                Ans.  Clustering model
                     d.  A grocery store wants to identify associations between different products purchased by customers to understand
                       which  products are  commonly bought  together.  They  have  a transaction  dataset  containing  records  of items
                       purchased together during each transaction.
                Ans.  Association model
                     Assertion and Reasoning Questions:
                     Direction: Questions 5-6, consist of two statements – Assertion (A) and Reasoning (R). Answer these questions by
                    selecting the appropriate option given below:
                     a. Both A and R are true and R is the correct explanation of A.
                     b. Both A and R are true but R is not the correct explanation of A.

                     c. A is true but R is false.
                     d. A is false but R is true.
                  5.  Assertion (A): Reinforcement Learning is a type of machine learning where a model learns through trial and error to
                    make the best decisions in a given environment.
                    Reasoning (R): In Reinforcement Learning, the agent interacts with the environment, receives feedback in the form of
                    rewards or penalties, and improves its actions based on that feedback.
                Ans.  a.
                  6.  Assertion (A):  The  Rule-based  Approach  is  one  of  the  earliest  and  simplest  methods  of  implementing  artificial
                    intelligence.
                    Reasoning (R): In the Rule-based Approach, decisions are made based on a set of predefined rules that dictate the
                    system’s actions.
                Ans.  a.
