To explain, there were 22 days on which there were 2 emergency calls, and 9 days on which there were 3 emergency calls. (a) Convert the frequency distribution to a probability distribution? Hint: Calculate the probabilities associated with the number of calls! (b) Is this an example of a discrete or continuous probability distribution? (c) What is the expected value (mean) number of emergency calls made daily? (d) What is the standard deviation of the number of emergency calls made daily? (e) What is probability of 3 emergency calls on a particular day? (f) What is probability of 2 or more emergency calls on a particular day? (g) What is probability of 1 or less emergency calls on a particular day
