The chart represents the sum of two dice rolled 50 times.

What is the difference between the theoretical probability and experimental probability of rolling a 10? (as a fraction)

A) 1/25
B) 11/75
C) 13/300
D) 19/ 300

$$\text{The experimental probability is }\dfrac{1}{25}\\ \text{The theoretical probability is } \dfrac{1}{12}$$

$$\dfrac {1}{12} - \dfrac{1}{25} = \dfrac{25-12}{300}=\dfrac{13}{300}$$
