Assume that the sales of Teri's Specialty Cakes has historically followed a normal distribution, with an average of 250 cakes per month, and a standard deviation of 15 cakes.
What is the probability that the sales for cakes will be no more than 285 over the next month?
Then can someone help me with this question also?
