The monthly utility bills in a city are normally distributed, with a mean of $100 and a standard deviation of $15. Find the probability that a randomly selected utility bill is (a) less than $69, (b) between $90 and $110, and (c) more than $130. (a) The probability that a randomly selected utility bill is less than $69 is 0.0192 (Round to four decimal places as needed.) (b) The probability that a randomly selected utility bill is between $90 and $110 is 0.4972 (Round to four decimal places as needed.) (c) The probability that a randomly selected utility bill is more than $130 is 0.0228|| (Round to four decimal places as needed.)
