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. P(child is healthy) = (Type an integer or a simplified fraction.) First Parent S S Second Parent S S Ss SS SS SS

Both flu and covid produce fevers. You know from past research that 10% of the population gets flu each year, but it is possible to get both covid and flu. Assume that the probability of getting flu and covid are independent. If this year the percentage of people reporting fever is 20%, what percentage of the population has covid? Studies show that due to similar transmission of flu and covid, someone who has covid has a 20% chance of also getting flu. What then is the probability of someone who has flu also having covid? Given the conditional information above, what is a better estimate of the percentage of people who have covid given the 20% fever reporting?

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 0.29.  The probability that Napoleon and Pedro catch the bus is 0.87. However, the probability that they make it to their first period class on time, given that they catch the bus is 0.81.  What is the probability that Napoleon and Pedro catch the bus and make it to their first period class on time?

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…
