Two dice are throw at the same time and the product of the numbers appearing on them is noted. Find the probability that the product is less than 9. |

Answer» Total number of all possible outcomes when two dice thrown together T(E) = 36. Product of the number on both dice is less than 9 so favourable outcomes are (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). `therefore " "F(E) = 16` `rArr" "P(E)=(F(E))/(T(E)) = (16)/(36) = (4)/(9)` |
