  11. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) (i) Random Experiment : It is a process which results in an outcome which is one of the various possible outcomes that are known to us before hand (ii) Sample Space : It is the set of all possible outcomes of a random experiment SUCCESS IN EE MAIN ER. VINEET LOOMBA (IIT RooRKEE)


  12. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Solved Example: Write the sample space of the experiment 'A coin is tossed, if it shows head a coin tossed again else a die is thrown Solution: The sample space S = {HH, HT, TI, T2, T3, T4, T5, T6) SUCCESS IN EE MAIN ER. VINEET LOOMBA (IIT RooRKEE)


  13. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Sample Point Each element of the sample space is called a sample point. Event An event is a subset of the sample space. When a die is rolled, sample space is S -1,2, 3, 4, 5, 6 Let A 1,3, 5), B- 2, 4, 6,, C 1, 2, 3, 4 A: Event of occurrence of an odd number, B: Event of occurrence of an even number C Event of occurrence of a number less than 5.

  14. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Mutually Exclusive or Disjoint Events: Two events are said to be mutually exclusive if occurrence of one of them rejects the possibility of occurrence of the other i.e. both cannot occur simultaneously e.g. In throw of a dice A- occurrence or even numbers and B-Occurrence of odd numbers SUCCESS IN JEE MAIN ER. VINEET LOOMBA (IIT RooRKEE)


  15. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Example: A coin is tossed three times, consider the following events. A: 'No head appears', B: 'Exactly one head appears' and C: 'Atleast two heads appear Do they form a set of mutually exclusive and exhaustive events? Solution The sample space of the experiment is S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} and A-(TTT), B {HTT, THT, TTH), C {HHT, HTH, THH, HHH) Now A u B u C = {TTT, HTT, THT, TTH, HHT, HTH, THH, HHH) = S Therefore, A, B and C are exhaustive events. Therefore, the events are pair-wise disjoint, ie, they are mutually exclusive. Hence, A, B and C form a set of mutually exclusive and exhaustive events SUCCESS IN JEE MAIN ER. VINEET LOOMBA (IIT RooRKEE)


  16. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Example: Two dice are thrown and the sum of the numbers which come up on the dice is noted. Let us consider the following events associated with this experiment A: 'the sum is even' C: the sum is less than 4. Which pairs of these events are mutually exclusive? B: "the sum is a multiple of 3. D: 'the sum is greater than Solution There are 36 elements in the sample space S {(, y): x, y 1, 2, 3, 4, 5,6) D (6, 6)) A n B-{(1, 5), (2, 4), (3, 3), (4, 2), (5, 1), (6, 6)) The pairs (A, C), (A, D), (B, C), (B, D) are not mutually exclusive events But C n D , so C and D are mutually exclusive events SUCCESS IN JEE MAIN ER.
