Chapter 6: Information Processing — Online MCQ Test

Q: Which diagram uses branches to show all possible outcomes of an event?

Answer: C. Tree diagram — A tree diagram uses branches to systematically represent all possible outcomes of events, making it easy to count combinations.

Q: A restaurant offers 4 types of appetizers and 5 types of main courses. How many different meals can be ordered with one appetizer and one main course?

Answer: B. 20 — Using the counting principle: 4 appetizers × 5 main courses = 20 different meal combinations.

Q: Analyze this scenario: You need to route data through 5 different checkpoints. At each checkpoint, data can take 2 different paths. Using information processing principles, what is the maximum number of different routes?

Answer: C. 32 — At each of 5 checkpoints, 2 path choices are available; using counting principle: 2 × 2 × 2 × 2 × 2 = 2⁵ = 32 different routes.

Q: Analyze this: A network must route data through 3 checkpoints. At checkpoint 1, there are 2 choices; at checkpoint 2, there are 3 choices; at checkpoint 3, there are 5 choices. However, the last choice at checkpoint 3 leads back to checkpoint 1. What is the maximum number of DIFFERENT first-pass routes (from checkpoint 1 to 3 without looping)?

Answer: B. 30 — For the first pass (without using the loop-back option), we count: 2 choices (checkpoint 1) × 3 choices (checkpoint 2) × 5 choices (checkpoint 3) = 30 different routes.
