Answer» Given that two dice are rolled.Then the total possible outcome n(S) = 6 × 6 = = 36Let E be the event of getting a product less than 9.The number whose product is less than 9are {1,1},{1,2},{1,3},{1,4},{1,5},{1,6},{2,1},{2,2},{2,3},{2,4}{3,1},{3,2},{4,1},{4,2},{5,1},{6,1} Favourable numbers = 16.Therefore the required probabilityP(E) = n(E)/n(S) = 16/36 = 4/9. |
