For the cage with 12 brown, 8 white, and 10 tan mice, if you remove two mice, what is the probability that both will be white? (Note: Sampling without replacement)
*Please show all work
2 mice from 30 can be selected in 30C2 ways
2 white mice from 8 can be selected in 8C2
Required probability = 8C2 / 30C2
= 28/435
= 0.0644

11. You are a researcher studying mice. You hypothesize allele, brown coat; B-dominant allele, black coat) and tail length (I recessive allele, shor allele, long tail) in mice are independently assorted. You know that both genes are autosomai gen. Youhve that genes that control coat color (b - recessive tail, L-dominant colonies of true- Obreeding access to two with short tails and brown coats. You cross the females and males described above and then you cross the F1s. Your aggregated...
In mice, black fur (B) is dominant to brown fur (b). At a different locus (C) allows the color deposition while (c) does not. Therefore, mice with cc genotype are albinos. If mice that are homozygous recessive for both characters are bred with mice who are heterozygous for both characters, what is the predicted phenotypic ratio of their offspring? PLEASE SHOW WORK, include legends and punnet squares! Thanks
Suppose that an urn contains 10 red balls and 4 white balls. Supposed 3 balls are drawn one by one from the urn. What is the probability of getting one red ball and two white balls? Show all work! a) Assume the balls are drawn with replacement. b) Assume the balls are drawn without replacement.
A box contains 12 white and 8 black marbles. Two balls are drawn out randomly from the box without replacement. Let X denote the number of white balls drawn out. a. Construct the probability distribution of X. b. Find mean and variance of X using the following formula ? = E (X) = ∑ ? . ?(?) ? ?(?2) = ∑ ?2 . ?(?) ? ?2 = ???(?) = ?(?2) − (?)2
An urn contains 12 white balls and 14 yellow balls. If you draw 4 balls without replacement, what is the probability of drawing 4 white balls?
Two balls are chosen from an urn without replacement. 3 are black and 4 are white. Find a) the probability that both of the balls are the same color b) given that at least one of the balls is white, what is probability that the other ball is white?
For this problem: In mice, a single gene controls yellow fur color. The Y allele is dominant and produces yellow fur, the y allele is recessive and results in white fur. When you cross two heterozgyous yellow mice (Yy x Yy), you find that you get 20 yellow offspring and 10 white offspring. That should tell you what kind of genetics and the probability of getting a single yellow or white mouse. What is the probability first picking a first...

1. 2. 3. A drawer contains black, brown, and white socks. How many
socks ensure two of the same color? With 2,0,3 and 6 how many three
digits even numbers can be generated without replacements? We
selected 20 persons by the random. What is the probability that
only 3 of them have the same birthday at August? Find the
probability that only 3 of them have the common month for their
birthday?

a) Two balls are drawn without replacement from an urn containing 12 balls, of which 7 are white and 5 are black. Find the probability that: (i) Both balls will be white (ii) Both balls will be the same color (iii) At least one of the balls will be white b) Repeat part (a) but with the balls drawn with replacement
