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 $68. (b) between $90 and $120, and (c) more than $150. (a) The probability that a randomly selected utility bill is less than $68 is - (Round to four decimal places as needed.) (b) The probability that a randomly selected utility bill is between $90 and $120 is - (Round to four decimal places as needed.) (C) The probability that a randomly selected utility bilis more than $150 is 0 (Round to four decimal places as needed.)
