(i) getting a multiple of 3
(ii) getting a number which is not a multiple of 3.

Answer

N/a

Explanation

In a throw of a dice
`S={1,2,3,4,5,6}`
`implies` No of possible outcomes `=6 `
(i) Favourable outcomes of getting a multiple of `3={3,6}`
No of favourable outcomes of a multiple of `3=2`
and probability of getting a multiple of `3=2/6=1/3`.
(ii) Favourable outcomes of getting a number which is not a of `3={1,2,4,5}`
`:.` No. of favourable outcomes `=4`
and required probability `=4/6=2/3`.
