Historically, there is a 25% chance of rain on any given day in April. Furthermore, on days when it rains, 80% of the time there are dark clouds in the morning. On days when it does not rain, 35% of the time there are dark clouds in the morning.
a) Construct a properly labelled tree diagram to represent this problem.
b) What is the chance of dark clouds in the morning on a random day in April?
c) Given that there are dark clouds in the morning, what is the chance that it will rain?

Suppose I have faith in my local weather reporter who says that the chance of rain tomorrow is 80 percent. Moreover, my friend, the seasoned sailor, tells me that whenever it rains the next day, the appearance of the sky visible this evening only appears about 10 percent of the time. Whenever there is a clear day, he adds, the present appearance of the sky occurs 60 percent of the time the evening before. Assume I trust my friends judgement,...

Data available from Weather Underground indicates that in Minneapolis in 2017, if there was pre cipitation on a given day, then there was approximately a 25% chance of precipitation the next day. On the other hand, if a given day had no precipitation, then there was a 30% chance there was no precipitation the next day. We want to use this data to forecast weather for this year (a) (6 points) Set up a Markov chain model to determine the...
Pink Panther Question D. Each day (independently of all other days) Jill has a 1/5000 chance of hearing a particular fact: let's say the fact that Henry Mancini composed "The Pink Panther Theme." Jill stores something in long term memory after hearing it 3 times. Use Poisson approximations to (approximately) answer the following (a) What is the probability that, by the time Jill is 10,000 days old, she knows that Henry Mancini wrote "The Pink Panther Theme"?
