                   Assertion and Reasoning Based Questions


                The following questions are Assertion(A) and Reasoning(R) based questions. Mark the correct choice as
                a.  Both A and R are true and R is the correct explanation of A
                b.  Both A and R are true and R is not the correct explanation of A
                c.  A is true but R is false
                d.  A is false but R is true
                Assertion(A):  A module is a collection of functions.
                Reasoning(R): A function is a sequence of instructions to perform a specific task.


                   Case Based Questions


               1.  Shikha is a computer programmer in an IT firm. Her company is organizing a Christmas carnival. One of the highlights of
                  the carnival is the lucky draw. She has been assigned the task of writing a program in Python that would randomly pick up
                  numbers from the given range for the lucky draw. Help her complete the task.
               2.  Rimjhim has recently studied statistics in class. Her maths teacher explained the concepts such as mean, median, and mode.
                  In the computer class, her teacher explained various functions of the statistics module that may be used for computing
                  these measures. To keep track of the pocket money of students studying in class, she decides to write a program that will
                  store the pocket money of students in the form of a list. Thereafter, using functions from the statistics module, she will
                  display the following output:
                  a. Average pocket money of the students of her class.
                  b. The median of the given data.
                  c. The amount of pocket money that is most common in the given data.
