**How Many Ways Can a Science Journalist Choose 4 Data Sets from 9, Including Exactly One of Two Specific Ones?** In an era where data shapes public understanding, journalists increasingly rely on carefully curated datasets to tell compelling, evidence-based stories. A growing question among science writers is: *How many ways can a journalist select four data sets from nine—including exactly one of two specific, high-impact datasets?* With rising public interest in transparency and factual storytelling, this problem reflects a broader trend: prioritizing precision and intentionality when using data to inform readers. Understanding how many combinations meet the “exactly one” condition reveals both mathematical clarity and strategic narrative choices. It’s not just a math exercise—it’s a framework for prioritizing depth over volume, and relevance over randomness. ---
