A beagle randomly selected: A) Find the probability that the weight is less than 23 pounds. B) Find the probability that the weight is between 23 and 25 pounds. C) Find the probability that the weight is more than 27 pounds. #2: Utility Bills: the monthly utility bills in a city are normally distributed with a mean of $100 and a standard deviation of $12. A utility bill is randomly selected: A) Find the probability that the utility bill is less than $70. B) Find the probability that the utility bill is between 90 and 120.
