There are two batsmen. Rahul's average is 50, Vijay's is 40. The coach says Rahul will definitely score more than Vijay in the next match because his average is higher. Is the coach's claim sound?
Who do you think is right? Pick one.
The answer: It cannot be said for sure
Why
The coach isn't wrong to lean on the average — 50 beats 40, and over MANY matches the higher average is the better bet. The word that breaks it is 'definitely', about ONE match. An average is a summary of many past innings smoothed together; it hides the ups and downs. Rahul's 50 could be 100 and 0; Vijay is steadier around 40. On any single day the low-average player can easily outscore the high one — that's why the game is played, not predicted. Test: a student averaging 80% can still score less than a 60% student on one particular test, on an off day. It cannot be said for sure: an average tells you the long-run tendency, never the certain result of a single next try.
