During the dry month of August, one U.S. city has measurable rain on average only two days per month. If the arrival of rainy days is Poisson distributed in this city during the month of August, what is the average number of days that will pass between measurable rain? What is the standard deviation? What is the probability during this month that there will be a period of less than two days between rain?

3. Let the amount of rain on rainy days be normally distributed with a mean of 3 cm and standard deviation of 1cm. (a) Find the probability that there is at least 2cm of rain on a randomly chosen rainy day. You can use a normal table to get the probabilities needed or use pnorm() in R. Do get a final answer that is numerical and not just a function of Φ(), the standard normal cdf. (b) Suppose on rainy...

On average Tempe, AZ gets rain 29 days a year (out of 365 days). Your weather app is predicting rain tomorrow. The app isn't perfect though. It only predicts that it will rain around 90% of the time that it actually does rain, and it will predict rain about 6% of the time that it doesn't rain. What is the probability it is going to rain tomorrow?
