Answer:
Explanation:
To find the experimental probability that the volcano will erupt in 1 or 2 in the next 5 decades, we need to analyze the data provided in the sets of random numbers generated.
From the given sets of random numbers, we can see that the number 1 represents the volcano erupting. We need to count the number of times the number 1 appears in the first or second position (representing the first or second decade) in each set.
Let's count the occurrences:
1. 3, 1, 2, 4, 2 (1 appears in the second position)
2. 3, 2, 2, 4, 5 (1 does not appear in the first or second position)
3. 1, 3, 3, 2, 5 (1 appears in the first position)
4. 5, 3, 4, 5, 4 (1 does not appear in the first or second position)
5. 5, 5, 3, 2, 4 (1 appears in the fourth position)
6. 2, 3, 3, 4, 2 (1 does not appear in the first or second position)
7. 1, 2, 4, 1, 4 (1 appears in the first and fourth positions)
8. 1, 3, 2, 1, 5 (1 appears in the first, third, and fourth positions)
9. 1, 2, 4, 1, 4 (1 appears in the first and fourth positions)
10. 5, 5, 3, 2, 4 (1 appears in the fourth position)
Out of the 10 sets, there are 6 sets where the volcano erupts in the first or second decade. Therefore, the experimental probability is 6 out of 10, which can be expressed as a fraction 6/10 or as a percentage 60%.
Based on the given answer choices, the closest option is D: 50%. However, the correct experimental probability is 60%.
