Question
**Using the Normal Distribution as an Approximation for the Binomial** In this example, we consider tossing a fair coin 20 times. We want to find the probability of getting between 9 and 11 heads. To solve this, we use the normal distribution as an approximation to the binomial distribution. **Key Details:** - Total coin tosses (n): 20 - Probability of heads (p): 0.5 - Between 9 and 11 heads inclusive After applying the normal approximation, the probability is calculated and rounded to two decimal places: **Probability: 0.49**
