A biologist studying Amazonian flora identifies 20 plant species in a region, 7 of which are endemic. If she randomly selects 8 species for genome sequencing, what is the probability that at most 1 endemic species is included?

**A biologist studying Amazonian flora identifies 20 plant species in a region, 7 of which are endemic. If she randomly selects 8 species for genome sequencing, what is the probability that at most 1 endemic species is included?** In a growing wave of ecological and genetic research, scientists are uncovering how rare plant species in remote Amazonian ecosystems hold keys to biodiversity, medicine, and climate resilience. Among the most intriguing discoveries: 20 distinct plant species in a single region, with 7 belonging exclusively to that area—endemic. When researchers randomly choose 8 species for detailed genetic sequencing, a calculated question emerges: what’s the likelihood that fewer than two endemic plants are included? This isn’t just a theoretical math puzzle—it speaks to how conservation data shape scientific insight and what it truly means to select species with precision. **Why This Question Matters in Current Scientific and Public Discourse**
