4.) Of all listeners who call the local radio station on the telephone, 60% are between the ages of 15 and 25. A random number generator is used to simulate 20 groups representing the next 6 listeners who will call the radio station. a.) What numbers could be used to represent the people inside and outside the 15 to 25 age range?

b.) Based on the trials below, what is the probability that the next six callers are all within the age range?
