To find the expected probability for each outcome, we first need to calculate the total number of results, which is the sum of the frequencies:
Total number of results = 10 + 9 + 6 + 15 + 13 + 8 = 61
Then, we calculate the expected probability for each outcome by dividing the frequency by the total number of results:
Expected probability:
2: 10/61 ≈ 0.164
4: 9/61 ≈ 0.148
6: 6/61 ≈ 0.098
8: 15/61 ≈ 0.246
10: 13/61 ≈ 0.213
12: 8/61 ≈ 0.131
Now, we compare the experimental probabilities with the expected probabilities:
Smallest discrepancy:
|0.164 - 0.164| = 0
|0.148 - 0.148| = 0
|0.098 - 0.098| = 0
|0.246 - 0.246| = 0
|0.213 - 0.213| = 0
|0.131 - 0.131| = 0
Therefore, the smallest discrepancy between the experimental and expected probability of this experiment is 0.
