Question Analysis  
This question combines mutually exclusive events and complementary events.
The main focus is calculating probability when one event excludes another.  

Key Concept Explanation  
Mutually Exclusive Events: Cannot happen at the same time (e.g., landing on red and not blue and red simultaneously). P(A or B) = P(A) + P(B)
Complementary Events: "Not landing on blue and red" includes green and yellow.  

Step-by-Step Solution  
1. P(Red) = 1/4.  
2. P(Not Blue and Red) = P(Green) + P(...
