2.  A school is organising a raffle where there are 10 tickets, and only one ticket is a winner. Each student gets one ticket.
                    What is the probability that a specific student wins the raffle?
                Ans.  Number of Favourable Outcomes = 1 (the winning ticket)
                     Total Number of Possible Outcomes = 10 (total tickets)
                                    1
                     Probability P(A) =    = 0.1 or 10%.

                    Assertion and Reasoning Question:
                      Direction: Question 3, consist of two statements – Assertion (A) and Reasoning (R). Answer these questions 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
                  3.  Assertion (A): Increasing the sample size generally leads to a more accurate estimation of probabilities.
                       Reasoning  (R):  Larger  sample  sizes  reduce  the  impact  of  random  variability,  leading  to  more  stable  and  reliable
                    probability estimates.
