Question: A science educator designs a digital learning module where students complete 7 sequential interactive tasks, each tagged with one of three difficulty levels: Easy (E), Medium (M), and Hard (H). If each task is assigned a difficulty uniformly at random, what is the probability that exactly two tasks are Hard and no two Hard tasks are consecutive?

**How Strategic Difficulty Sequencing Optimizes Learning In Digital Education** In today’s fast-paced digital learning landscape, educators increasingly rely on structured sequencing to enhance student engagement and mastery. A growing number of science educators design interactive modules composed of sequential tasks—each tagged by difficulty level. Among common configurations, one intriguing pattern emerges: creating 7 tasks with exactly two Hard challenges, carefully spaced so no two are consecutive. This raises a clear, data-driven question: What’s the probability of this pattern when each task’s difficulty is assigned randomly? Beyond probability, understanding the structure reveals how thoughtful task design drives better learning outcomes—particularly when difficulty varies with intention. --- ### Why This Question Matters: Trends Shaping Digital Education
