Marks: +1, -0

Solution:

Concept:

The probability of no difference means the two dice show the same number.

Explanation:

Total possible outcomes when two dice are rolled =

6 \times 6 = 36

The outcomes with no difference (difference = 0) are

(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)

Number of favorable outcomes = 6.

Required probability =

\frac{6}{36} = \frac{1}{6}

Answer:

\frac{1}{6}
