13. Two dice, one white and one red are rolled together. Find the probability of getting(iii) a difference of $1$.

(iii)

The probability that getting a difference of $1$,

Favorable outcomes $=(1,2),(2,1),(2,3),(3,2),(3,4),(4,3),(4,5),(5,4),(5,6),(6,5)$

Number of favorable outcomes $=10$

P(getting a sum of $6$) = Number of favorable outcomes/total number of Outcomes

$=10/36$

$=5/18$
