In this example 100 people are selected at random and asked if they exercise frequently. Let's assume 30% of the 100 people exercise frequently. 1. What is the probability that exactly 40 people exercise frequently? 2. What is the probability that more than 40 people exercise frequently? 3. What is the probability that less than 40 people exercise frequently? 4. What is the probability that between 30-50 people exercise frequently
