Question Analysis
This question involves using a frequency table to calculate the probability of a compound event where the event is an “or” relationship between two categories.
The main focus is on correctly identifying the relevant frequencies of the two categories (apple and orange), summing them up, and then dividing by the total frequency to obtain the probability.
Key Concept Explanation
