Sickle cell anemia is an inherited disease in which red blood cells become distorted and deprived of oxygen. A person with two sickle cell genes will have the disease, but a person with only one sickle cell gene will have a mild, non- fatal anemia called sickle cell trait. Using S to represent a healthy gene, and s the sickle cell gene, the table shows the four possibilities for the children of two Ss parents. Find the probability that these parents give birth to a child who is healthy. That is, the child does not have the disease or trait.

Based on a study from the Chronicles of Flippin'' Awesomeness, the probability that Napoleon and Pedro make it to their first period class on time is 0.37.  The probability that Napoleon and Pedro catch the bus is 0.66. However, the probability that they make it to their first period class on time, given that they catch the bus is 0.61.  What is the probability that Napoleon and Pedro catch the bus and make it to their first period class on time?

Analysts expects that 11% of all publicly traded companies will experience a decline in earnings next year. If a company is headed for a decline, there is a 74% chance that this ratio will be negative. If the company is not headed for a decline, there is only a 20% chance that the ratio will be negative. The analyst randomly selects a company and its ratio is negative. What is the probability that the company will experience a decline?

A pharmaceutical company is running trials on a new test for anabolic steroids. The company uses the test on 400 athletes known to be using steroids and 200 athletes known not to be using steroids. Of those using steroids, the new test is positive for 375 and negative for 25. Of those not using steroids, the test is positive for 25 and negative for 175. What is the relative frequency of a false negative result (the probability that an athlete using steroids will test negative)? (Round your answer to two decimal places.) What is the relative frequency of a false positive result (the probability that an athlete not using steroids will test positive)? (Round your answer to two decimal places.)

A survey found that 40% of Dynamic Housing’s potential customers viewed the single-family house virtual tours and of those that viewed the virtual tours 3% leased a single-family house. What is the probability that a potential customer will view the virtual tour and lease a single-family house.

You are a physician meeting with a patient who has just been diagnosed withcancer. You know there are two mutually exclusive types of cancer that the patientcould have: type A and type B. The probability that she has type A cancer is 1/3. TypeA is deadly: four patients out of five diagnosed with type A cancer die within one year.Type B is less dangerous: only one patient out of five diagnosed with type B cancerdies within one year. What is the probability that your patient has type A cancer and suc-cessfully survives it? What is the probability that your patient dies within a year? Suppose that your patient dies in less than one year before you learn the exact type of cancer he has. Given this sad happening, what is the probabilitythat she had type A cancer?   (Hint: You want to start off by considering this question: given the informationprovided in the story (what those numbers are really about?), which of the twoanalytical tools we have covered in class will be more helpful to solve…

A manufacturer makes two models of an item: model I, which accounts for  75% of unit sales, and model II, which accounts for 25% of unit sales. Because of defects, the manufacturer has to replace (or exchange)  5% of its model I and 10% of its model II. If a model is selected at random, find the probability that it will be defective. Please round the final answer to  2 or 3 decimal places. P(detective)=
