Question

What is the probability when two unbiased dice are rolled to get their product divisible by 3

Answer 1

Dear student,

$$\begin{gathered} Numberoffavourableoutcomes=(1,3),(1,6),(2,3),(2,6),(3,1),(3,2),(3,3), \\ (3,4),(3,5),(3,6),(4,3),(4,6),(5,3),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)=19 \\ Probability=\frac{Numberoffavourableoutcomes}{Totalnumberofoutcomes}=\frac{19}{36} \end{gathered}$$
