Three people are suspected of robbery of a hardware store: Alex, Ben, and Saleh. Preliminaryinvestigation by the police has led to the following conclusions:(i)If Saleh is involved in the crime, then Ben is also involved.(ii)If Alex is guilty, then Ben is also guilty.The first conclusion of the preliminary investigation turned out to be true, and the second turnedout to be false.

The player pays a fee of $5 to play. The player then rolls a 12-sided die three times. If the player rolls a 7 on any of the three rolls, they win a prize. The prize is determined by the number of 7s rolled. If the player rolls one 7, they win $5. If the player rolls two 7s, they win a $10. If the player rolls three 7s, they win $20. Give evidence that the player will theoretically win 20-40% of the time

5) It is the first day of school and Ms. Adams, the first-grade teacher, wants all of her students to shake hands with each other.

Part 1: Should We Convict? A woman who was shopping in Los Angeles had her purse stolen by a young, blonde female who was wearing a ponytail. The blonde female got into a yellow car that was driven by a white male who had a mustache and a beard. The police located the blonde female named Janet Collins who wore her hair in a ponytail and had a friend who was a white male who had a mustache and beard and also drove a yellow car. The police arrested the two subjects. Because there were no eyewitnesses and no real evidence, the prosecution used probability to make its case against the defendants. The probabilities below were presented by the prosecution for the known characteristics of the thieves. Characteristic Probability Yellow Car 1/10 Man with Mustache 1/4 Woman with a Ponytail 1/10 Woman with Blonde Hair 1/3 White Man with Beard 3/10 Man & Woman in car 1/100 Assuming that the characteristics listed are independent of each other, what is the probability that…
A report in the college newsletter used the registrar's database for all the students in the school to look at majors and classes being taken this semester. The report includes the sentences:
Anthony has just received Covid-19 test results from a patient named Melania. The accuracy of the test is as follows: the probability the test will be positive if Melania has Covid-19 is p, and the probability the test will be positive if Melania does not have Covid-19 is q. The proportion of the population that has Covid-19 is 7. The test comes back positive. Anthony has no information about Melania's symptoms. (For reasons he does not understand.) wiet value of ya would result in the simple model of base-rate neglect we learned in class? 67 O 33 25 Problem If p = .95, q = .05, and a = .1, what must be the value of y if Anthony believes that the probability Melania has Covid-19 is .9? 3.214 O 1.05 O 3.57
After an earthquake, 32 homes in a remote area were checked by public safety officers before nightfall. They found that 22 of the houses had no gas, including 10 houses whose own gas lines were damaged. (A house loses its gas service if it has damage to its own line or if there is damage to the feeder line.) Of those houses that lost their gas, only 4 did not lose their electricity. Twenty-four houses in all had no electricity, the same number of them lost only their electricity as those that both lost electricity and had damage to their gas lines. How many of the houses checked did not lose either gas or electricity, and how many lost only their gas service! Students, draw anywhere on this slide!
1)Bob Neverready has a portable TV. The TV uses two batteries and both of them are dead. Bob opens a new pack of four good batteries and dumps them on the table. Then he opens the TV and dumps the two dead batteries on the table with the good ones. The batteries get mixed up and Bob no longer knows which are which. (Has this ever happened to you?) If Bob picks two batteries off of the table at random and puts them into the TV, what is the probability that he chose two good batteries and that the TV will work? The average unemployment rate in California in August 2020 was 11.4%. 2)Assume that 550 employable people in California were selected randomly in August 2020.

Convicted by mistake In criminal trials (e.g., murder, robbery, driving while impaired, etc.) in the United States, it must be proven that a defendant is guilty beyond reasonable doubt. This can be thought of as a very strong unwillingness to convict defendants who are innocent. In civil trials (e.g., breach of contract, divorce hearings for alimony, etc.), it must only be proven by a preponderance of the evidence that a defendant is guilty. This makes it easier to prove a defendant guilty in a civil case than in a murder case. In a high-profile pair of cases in the mid 1990s, O. J. Simpson was found to be not guilty of murder ina criminal case against him. Shortly there- after, however, he was found guilty in a civil case and ordered to pay damages to the families of the victims. a. In a criminal trial by jury, suppose the probability the defendant is convicted, given guilt, is 0.95, and the probability the defendant is acquitted, given innocence, is 0.95. Suppose that 90% of all…
n an unsolved airplane hijacking case from 1971, the hijacker (given the alias of D. B. Cooper) parachuted out of the back of a Northwest Boeing 727 over the southwest part of Washington State with $200,000 in $20 bills strapped to his body. The money and four parachutes had been provided by the FBI after Cooper took over the plane, claiming to have a bomb. Despite an intensive search by the FBI and 400 troops from Fort Lewis near the projected landing spot, Cooper was never found and his fate remains unknown. The combined weight of Cooper, the money, and his parachutes was approximately 230 lbs. He jumped from an altitude of 10,000 feet. Assume a linear drag term of −cv (where c is the drag coefficient and v is the velocity), and assume that he opened his parachute instantaneously 30 seconds after he stepped out of the plane and that his drag coefficient was c = 1.1 lbs-sec/ft before the chute opened and c = 12 lbs-sec/ft after. Estimate the speed (in ft/s) with which he hit the…
Ann, Jim, John, and Nancy are scheduled to compete in a racquetball tournament. Ann is twice as likely to beat Jim, and Jim is the same level as John. Nancy's past winning record against John is one out of three. Set the problem up in terms of the probablity of Nancy winning the tournament and solve the questions: a. What is the probablity that Jim wins the tournament? b. What is the probablity that a woman will win?
