1. Assume your computer network may have been hacked and computers may have 2 different typesof viruses (virus type-A and virus type-B). The current situation shows that 15% of computers end upwith type-A virus, 10% end up with type-B virus, and 10% of the computers infected with type-A ortype-B virus have both viruses.1.a) Compute the probability that a computer is infected with both viruses1.b) Compute the probability that a computer has type-B virus given that it has type-A virus

Sickle cell disease is an inherited blood disorder that affects red blood cells. Since it is a recessive disorder, a person inheriting two sickle cell genes will have the disease, whereas a person inheriting only one sickle cell gene will be healthy, but will carry the sickle cell trait. If both parents have the sickle cell trait, and it is equally likely whether a parent passes on the gene for sickle cell trait, determine the probability that an offspring will have the disease. an offspring will have the sickle cell trait. an offspring will have neither sickle cell anemia nor the sickle cell trait.
Only 6% of people has 0-negative blood type. If a local blood drive has 100 donors, what is the probability that at least 10 of the 100 donors has O-negative blood?
A particular team sport declares the team that wins 4 games out of 6 possible games as the champion. The championship ends once a team has won 4 games. Suppose that teams X and Y face each other in the championship games and that team X has 65% probability of winning a game over team Y. What is the probability that team X wins the championship in 5 games?
There is a 50% chance that a father carries the gene of a certain disease. If he is a carrier, then each of his children has a 50% chance of having the disease independently. If the father is not a carrier, a child will not have the disease. Suppose the father has had three children without the disease. What is the probability the father is a carrier?

What is the probability of finding an H2O based compound with a blue label in a storage facility of 1,000 vials. We know there are 22 vials of H2O based compound in the facility, and that 800 of the total number of vials in the facility have blue labels.
A company buys microchips from three suppliers I, II and III. Supplier I has a record of providing microchips that contain 10% defective; supplier a defective rate of 5% and supplier III has a defective rate of 3%. Suppose 10%, 40% and 50% of the current supply came from suppliers I, II and III, respectively. If a randomly selected microchip is defective, what is the probability that it came from supplier II? Express your answer accurate to two decimal places. O 48 O..40 O something else O 44 O 41
Suppose we build a taco-making machine. But there is a fatal flaw in the machine, where for each taco made, there's a 5% chance that it's actually a toxic taco. If the machine makes 100 tacos, what is the probability that at most 2 of them are toxic?
In a specific type of electronic card, the probability of a transistor being defective is 0.01. Let's assume there are 200 transistors on the electronic card. If there are no defective transistors, the electronic card is considered to be functioning. What is the probability of any electronic card not functioning?

Data from Office on Smoking and Health, Centers for Disease Control and Prevention, indicate that 35% of adults who did not finish high school, 33% of high school graduates, 22% of adults who completed some college, and 12% of college graduates smoke. Suppose that one individual is selected at random and it is discovered that the individual smokes. Use the probabilities in the following table to calculate the probability that the individual is a college graduate. Education Not a high school graduate 0.0975 High school graduate Some college, no degree Employed Unemployed 0.0080 Associate Degree Bachelor Degree Advanced Degree 0.3108 0.1785 0.0849 0.1959 0.0975 0.0128 0.0062 0.0023 0.0041 0.0015 Probability = | proportion of Hints: This problem has all the information you need, but not in the typical ready-to-use form.

In a study of 213,270 cell phone users, it was found that 77 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000397 probability of a person developing cancer of the brain or nervous system. We therefore expect about 85 cases of such cancer in a group of 213,270 people. Estimate the probability of 77 or fewer cases of such cancer in a group of 213,270 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(x ≤ 77) = (Round to four decimal places as needed.)
