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?

1. In St. Louis, the average amount of rainfall in June is 4.3 inches (meaning the daily mean is 4.3/30 inches). On average, 20 days of June experience no rain at all (meaning the probability of 0 inches of rain on any June day is 20/30). Assume the pdf of inches of rainfall per day is exponential, so that the pdf has the form below. (a) Find a and b (so that E(X)-4.3/30) (b) What is the chance of getting...
Consider the following events: R - it will rain tomorrow (same as on any given day of the year) Rc - it will not rain tomorrow F - tomorow's forcast says it will rain Here is what we know from the past: P(R) = 0.25 (25% of the days were rainy) P( F | R ) = 0.85 (85% of the rainy days were corectly predicted) P( F | Rc ) = 0.20 (20% of the not rainy days had...
