Question

six faces of a die are shown in the figure
A B C D E A
the die is rolled once , fill in the boxes
s=_. n(s)=_
let A be the event that C appears on upper face
A={C}. n(A)= _
p(A)= n(A)/n(S) =

​

Answer 1

Answer:

A

(1) 'A' appears on upper face.

B

(2) 'D' appears on upper face.

Answer

A::B::C

Solution

The die is rolled once.

S={A,B,C,D,E,A} ∴n(S)=6

(1) Let 'A' appear on the upper face

ThenA={A,A} ∴n(A)=2

P(A)=n(A)n(S)=26=13

(2) Let 'D' appear on the upper face.

ThenD={D} ∴n(D)=1

P(D)=n(D)n(S)=16.
