Solution
The number of possible outcomes is `6xx6=36`, We write them as given below:
1,11,21,,31,41,51,6
2,12,22,32,42,52,6
3,13,23,33,43,53,6
4,14,24,34,44,54,6
5,15,25,35,45,55,6
6,16,26,36,46,56,6
n(s)=36
E= Event of getting a number less than 3 on eacch dice
={(1,1))(1,2)(2,1)(2,2)}
n(E)=
Probability of getting a number less than 3 on each dice = `(n(E))/(n(s))=4/36=1/9 `
