A man and woman agree to meet at a certain location at 12:32 pm. If the man arrives at a time that is uniformlydistributed between 12:19 pm and 12:46 pm, and if the woman arrives independently at a time that is uniformlydistributed between 12:00noon and 1:00 pm, what is the probability that the man arrives first?

The probability that the man arrives first is the area of this region divided by the total area of…

Suppose that the probability of rain today depends on weather conditions form the previous three days. If it has rained for the past three days, then it will rain today with probability 0.7; if it did not rain for any of the past three days, then it will rain today with probability 0.1; if it rained each of the past two days but not three days ago, it will rain with probability 0.8; and, in any other case, the weather today will match yesterday's weather with probability 0.6. Provide the Markov Chain for the above system in form of state space and the transition probabilities.
Erik, Jordan, Adam, Myra, Gabriel, and Johanna have all been invited to a dinner party. They arrive randomly and each person arrives at a different time. Find the probability that Adam arrives first and Erik arrives last.
A bowl with Christmas candy contains two types: 7 different individually wrapped cookies and 14 different fun-size candy bags. If 6 of these are selected at random by grabbing a handful of these goodies from the bowl, what is the probability that this selection contains 2 cookies and that the rest are fun-size candy bags? (Note: No need to bring your answer in lowest terms. Give the answer as a fraction or as a decimal rounded to four decimal places.)
Suppose that an employee at a local company checks his watch and realizes that he has 10 minutes to get to work on time. If he leaves now and does not get stopped by any traffic lights, he will arrive at work in exactly 8 minutes. In between his house and his work there are three traffic lights, A, B, and C. Each light that stops him will cause him to arrive an additional 2 minutes later. The following table displays the probability that he is stopped by each of the three traffic lights. Assume that the probability that he is stopped by any given light is independent of the probability that he is stopped by any other light. Traffic light A Traffic light B Traffic light C ?(?)P⁡(A) ?(?)P⁡(B) ?(?)P⁡(C) 0.6 0.4 0.9 What is the probability that the employee is not late for work? (Round to 3 decimal places)
Industrial Robots are programmed to operate through microprocessors. The probability that one such computerized robot breaks down during any one 8-hour shift is 0.2. Find the probability that the robot will operate for at most five shifts before breaking down twice.
A factory received a shipment of 16 lightbulbs, and the vendor who sold the items knows there are 4 lightbulbs in the shipment that are defective. Before the receiving foreman accepts the delivery, he samples the shipment, and if too many of the lightbulbs in the sample are defective, he will refuse the shipment.For each of the following, give your responses rounded to the eighth decimal.If a sample of lightbulbs is selected, find the probability that all in the sample are defective.(answer) If a sample of 4 lightbulbs is selected, find the probability that none in the sample are defective. (answer)
A box has 8 blue and 6 green jelly beans. A bag has 3 blue and 5 green jelly beans. A jelly bean is selected at random from the box and placed in the bag. Then a jelly bean is selected at random from the bag. If a green jelly bean is selected from the bag, what is the probability that the transferred jelly bean was green? (Round your answer to three decimal places.)
Every cereal box has a gift inside but you cannot tell from the outside what the gift is. The store manager assures you that 20 of the 57 boxes on the shelf have the secret decoder ring. The other 37 boxes on the shelf have a different gift inside. If you randomly select two boxes of cereal from the shelf to purchase, what is the probability that BOTH of them have the secret decoder ring? (Give answer as a decimal correct to four decimal places.)

A certain disease has a prevalence of in a population. The rate of false 4 positives is 10% and and the rate of false negatives is 5%. If you are exposed to the disease, then probability that you contract it is . You can only contract the disease by sharing food. Suppose that you meet 10 people, that each person tests negative for the disease, and that you share food with each of them exactly three times. What is the probability that you contract the disease?
In a group of 25 people, a person tells a rumor to a second person, who in turn tells it to a third person, and so on. Each person tells the rumor to just one of the people chosen at random, excluding the person from whom he/she heard the rumor. The rumor is told 10 times. What is the probability that the rumor will not return to the originator?
