Question: A pharmacologist is testing combinations of 3 distinct drug compounds selected from a library of 10, where 4 are known to interact synergistically. What is the probability that a randomly chosen set of 3 compounds includes at least one synergistic pair?

**How Pharmacologists Analyze Drug Synergies—And Why It Matters for Drug Discovery** When breakthrough treatments rely on precise molecular combinations, understanding how drugs interact is more critical than ever. In the US pharmaceutical research sector, scientists increasingly explore combinations of three compounds from a library of 10, where 4 are known to work synergistically to enhance therapeutic effects. But beyond lab experiments, a key statistical question emerges: what’s the probability that a randomly selected trio includes at least one synergistic pair? This inquiry reflects broader trends in data-driven drug design and predictive analytics within modern pharmacology. **Why This Question Matters Now** The rise of precision medicine and combination therapies has intensified scientific interest in synergistic drug interactions. With pressure to deliver faster, safer, and more effective treatments—especially in oncology and rare diseases—researchers turn to combinatorial screening. Meanwhile, the growing volume of open-access pharmacology studies has sparked curiosity about how to quantify interaction probabilities across large compound libraries. This question isn’t just academic; understanding key probabilities behind
