It's 75 degrees and sunny here in San Diego this afternoon...," the weatherman droned on, repeating a phrase that probably should have been recorded and played on an endless loop. Tim looked at the previous year's high temperatures and noted that the average was 78 degrees with a standard deviation of 1 degrees and approximated a normal distribution. Armed with this evidence, determine:
(a) the probability of a daily temperature between 78 degrees F and 79 degrees F.
(b) the probability that the daily temperature exceeds 78 degrees F.
(c) the probability that the daily temperature is below 78 degrees F.
