In purebred Labrador retrievers, the dominant fur-color allele, B, results in black fur, and therecessive allele, b, results in yellow fur. Suppose the Happy Labrador Ranch breeds yellowand black Labrador retrievers. The Ranch is expecting a new litter of four puppies, and theowners want to calculate the probability that the puppies will be either all black or two will be BB or Bbbbblack and two will be yellow. The parents of the new litter are both black and heterozygous,Bb, for coat color.Calculate the probability that the new puppies will be either all black or two will be black and two will be yellow. Enter theprobability as a decimal rounded to the nearest thousandth.probability:

Given : P(black puppy) = 24 P(yellow puppy) = 24

Answered: In purebred Labrador retrievers, the…

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.

It is estimated that 1% of the population has a certain genetic defect. A medical test is used to determine if people have this defect and, if a person has this defect, the test will correctly indicate this with probability 90%. However, if a person does not have this defect, the test will still indicate that he or she has the defect with probability 9.6%. If a person tests positive for this defect, what is the probability that the person actually has the defect? Express your answer, rounded to three decimal places, if necessary.
The blood-typing system is based on the presence or absence of antigens. A person with antigen A has blood type A. A person with antigen B has blood type B, and a person with both antigens has the blood type AB. If there are no antigens, then the blood type is O. In addition, blood types are also identified as Rh-positive or Rh-negative based on a different antigen. What is the probability that a person has the A antigen or is Rh-positive?

A mother and father with normal color vision have six male children, two of whom exhibit red- green colorblindness. Their five female children all exhibit normal color vision. Ignoring the fact that these parents ought to seek some family planning advice, what is the probability that their 12th child will be another colorblind boy? (Hint: colorblindness is an X-linked trait in humans.) Select one: a. 1/6 b. 1/4 c. 1/3 d. 1/8 e. 1/2
An insurance company issues policies of two types - 20% are of type A and the remainder are of type B. For the type A policies, 36% of the policyholders are female, while for type B policies, 16% of policyholders are male. If a policy is selected at random from those held by females, what is the probability that it is a type A policy?
In a study it was discovered that 27% of the paintings in a certain art gallery are not original paintings, but fakes. A collector in 15%of the cases makes a mistake in judging if the painting is authentic or a fake. If she buys a piece thinking that it is an original, what is the probability that it is not?
On Mr. Casper's debate team at Thunderbird High School, 20% of the members are Sophomores, 35% are Juniors and 45% are Seniors. A team member is selected randomly to give the closing argument for the team. If a sophomore gives the closing argument, the team has a probability of 0.25 of winning the debate. If a junior gives the closing argument, the probability of winning is 0.6. If a senior closes, the probability of winning is 0.85. (a) Find the probability that the team wins the debate. b sketch a tree diagram to model this process
3. Draw a 4-color spinner (red, green, yellow, blue) such that landing on green is twice as likely as landing on red; landing on yellow is equally likely as landing on green; landing on blue is more likely than landing on yellow.
