=36.
(i)P(doublet) :
The favorable outcomes ={(1,1),(2,2),(3,3),(4,4),(5,5),(6,6)}
Number of favorable outcomes =6
∴ Probability of getting a doublet =P(doublet)=
36
6
=

.
(ii)P(sum=10) :
The favourable outcomes ={(4,6),(5,5),(6,4)}
Number of favorable outcomes =3
∴ Probability of getting a sum 10 =P(sum=10)=
36
