An ornithologist tracks 12 migratory birds fitted with GPS tags. Each bird follows one of three migration routes: Route A (4 birds), Route B (5 birds), or Route C (3 birds). Due to weather anomalies, birds on Route A are 1.5 times more likely to be delayed than those on Route B, and birds on Route C are twice as likely as Route B. If delays occur independently, and each route has a base delay probability p, express the expected number of delayed birds across all routes in terms of p. - Appfinity Technologies
