Premier League Predictor: Astro — Chapter 1, Exercise 1
====================================================

TASK
Explain the real difference between a "correct score" and a "correct
result" prediction, and describe one real scenario where a prediction
earns the 10-point correct-result score but not the 40-point
correct-score bonus.

SOLUTION

A "correct score" means the predicted scoreline matches the actual
final score exactly — both numbers, for both teams. A "correct
result" only requires that the predicted outcome category (home win,
away win, or draw) matches the actual outcome, regardless of whether
the exact numbers line up.

Every correct score is automatically also a correct result, but a
correct result is not automatically a correct score — the two are
scored independently, and only the exact-match case earns both the
40-point correct-score bonus and the 10-point correct-result points.

Worked example:
  Actual result:      Arsenal 2, Chelsea 1
  Predicted:           Arsenal 3, Chelsea 1

  - The predicted outcome (a home win for Arsenal) matches the real
    outcome (a home win for Arsenal) -> correct result, worth 10
    points.
  - The predicted scoreline (3-1) does not match the actual scoreline
    (2-1) -> not a correct score, so the 40-point bonus is not
    awarded.

Total for this prediction: 10 points, not 50.

WHY THIS WORKS AS AN ANSWER
----------------------------
It states the real definitional difference (exact scoreline vs.
outcome category), explicitly notes that a correct score always
implies a correct result but not the reverse, and gives one concrete,
numbers-based example showing a real case where only the smaller
10-point award applies rather than the full 40 — exactly what the
exercise asked for.
