Solution
The correct option is
A
1
36
Solution:- (A)
1
36
Let
A
be the event that the same no. will appear on each of the dice.
Three dice can fall in
216
ways.
Thus,
n
(
S
)
=
216
If the same number appears on each of them then the possible number of ways is
6
.
Thus
n
(
A
)
=
6
∴
P
(
A
)
=
n
(
A
)
n
(
S
)
=
6
216
=
1
36
Hence the probability that the same number will appear on each of them is
1
36
.
