To compare Sadiq's experimental probability to the theoretical probability of rolling an even number on a six-sided die, we first determine each probability.

Theoretical Probability: On a six-sided die (with faces numbered 1 through 6), the even numbers are 2, 4, and 6. Thus, there are 3 favorable outcomes for rolling an even number. The theoretical probability of rolling an even number is calculated as follows:

\[ \text{Theoretical Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total possible outcomes}} = \frac{3}{6} = \frac{1}{2} = 0.5 \]

Experimental Probability: Sadiq rolled the die 10 times and got an even number 7 times. The experimental probability can be computed as follows:

\[ \text{Experimental Probability} = \frac{\text{Number of times an even number was rolled}}{\text{Total number of rolls}} = \frac{7}{10} = 0.7 \]

Comparison: Now we compare the experimental probability (0.7) with the theoretical probability (0.5):

  • Experimental Probability: 0.7
  • Theoretical Probability: 0.5

Since 0.7 (experimental) is greater than 0.5 (theoretical), the correct response is:

The experimental probability was greater than the theoretical probability.
