To find the probability that more than 3 individuals weigh more than 20 pounds, we can model the problem using a binomial distribution. If you know the total number of individuals and the probability of one individual weighing more than 20 pounds, you can calculate this probability using the cumulative binomial formula. Remember, you'll need to find \(1 - P(X \leq 3)\) to get the probability that more than 3 individuals weigh more than 20 pounds. In practice, binomial problems often involve the concept of a "success" or "failure." Identifying what constitutes a successful outcome (in this case, someone weighing more than 20 pounds) can help streamline your calculations. Common mistakes involve confusing the total number of trials with the successful outcomes, so take a moment to clarify your variables before diving in!
