Text Solution

Verified by Experts

The correct Answer is:
A, B, C
The die is rolled once.
`S={A,B,C,D,E,A}" "thereforen(S)=6`
(1) Let 'A' appear on the upper face
`ThenA={A,A}" "thereforen(A)=2`
`P(A)=(n(A))/(n(S))=(2)/(6)=(1)/(3)`
(2) Let 'D' appear on the upper face.
`ThenD={D}" "thereforen(D)=1`
`P(D)=(n(D))/(n(S))=(1)/(6).`
