Please show all work so I can understand! Thank you!
A) John Has observed that the daily revenues from his coffee house follow normal distribution with 175 dollars. mean μ = 550 dollars and standard deviation o = Find the probability that the revenues for a day chosen at random will be between $500 and $600 B) People who used internet spend in average = 36 dollars with standard deviation o = 10 dollars per month. Amount spent for internet follows normal distribution. Calculate the probability that the sample of 64 people who use the internet spend in average less than $40 per month.
