Answer
Correct Answer: 60
Explanation
Introduction / Context:We perform independent choices from disjoint categories (oranges, mangoes, bananas). The total number of selections is the product of independent counts.
Given Data / Assumptions:
- Oranges = 5, Mangoes = 4, Bananas = 3.
- Choose exactly one from each category.
Concept / Approach:Use the multiplication principle across independent categories: total ways = 5 * 4 * 3.
Step-by-Step Solution:5 * 4 * 3 = 60.
Verification / Alternative check:Enumerating choices per category confirms the product.
Why Other Options Are Wrong:120 doubles the count (perhaps ordering); 110 and 75 are unrelated combinations.
Common Pitfalls:Confusing selection (unordered) with arrangement (ordered) across categories.
Final Answer:60
