Question

Two dice are thrown simultaneously. The probability of obtaining a total score of $8$ is $k/36$.Find $k$

Answer 1

Total possibilities $=n\left(S\right)=6\times 6=36$
Favorable outcomes : $(2,6),(3,5),(4,4),(5,3)$ and $(6,2)$ $\Rightarrow n\left(E\right)=5$
The probability$=\frac{5}{36}$
$\Rightarrow k=5$
