Question Analysis
This question involves probability from numerical data by counting values greater than a threshold.
The main focus is to identify scores >85 and calculate their proportion.
Key Concept Explanation
Probability for numerical conditions:
1. Count data points meeting the condition (here, >85).
2. Divide by the total number of data points.
Step-by-Step Solution
1. Total scores = 6
2. Scores >85: 90, 95 (2 values)
