It is known that 35% of the mice inoculated with a serum are protected from certain disease. If 7 mice are inoculated, find the probability that at most 1 mouse survive the disease.
Homework Answers
X ~ Binomial (n,p)
Where n = 7 , p = 0.35
P(X) = nCx px (1-p)n-x
P( X <= 1) = P (X = 0) + P (X = 1)
= 7C0 0.350 0.657 + 7C1 0.351 0.656
= 0.2338

The HIV disease can be produced by three viruses (A, B, C). For mice, the probability of developing the disease if infected with the virus A is 1/3, with virus B is 2/3 and virus C is 1/7. a) if a researcher inoculates a mouse with one of the viruses at random, what is the probability that the mouse develops the disease? b) If a mouse is inoculated and develops the HIV disease, what is the probability that it was...

In a group of 45 mice, there are 10 that have a certain genetic character. suppose that 7 mice are randomly selected ( 7 different mice are chosen - a single mouse cannot be chosen more than once). what is the probability that there is at least one mouse with genetic character in the 7 randomly selected mice ? please explain and answere !!!!

7. In mice the coat color called agouti results from a dominant allele A. Mice that are AA or Aa have agouti fur. Mice that are aa have black fur. However to get any coat color at all, at least one copy of a second dominant allele C of a different locus must be present. If a mouse has genotype cc, the mouse is albino regardless of what is happening at the other gene pair. Suppose two mice with genotypes...

A certain medical test is known to detect 51% of the people who are afflicted with the disease Y. If 10 people with the disease are administered the test, what is the probability that the test will show that: All 10 have the disease, rounded to four decimal places? At least 8 have the disease, rounded to four decimal places? At most 4 have the disease, rounded to four decimal places?
A diagnostic test for a certain disease is applied to n individuals known to not have the disease.
A diagnostic test for a certain disease is applied to n individuals known to not have the disease. Let X the number among the n test results that are positive (indicating presence of the disease, so X is the number of false positives) and p = the probability that a disease-free individual's test result is positive (i.e., p is the true proportion of test results from disease-free individuals that are positive). Assume that only X is available rather than the...

A total of 12 mice are sent down a maze, one by one. From previous experience, it is believed that the probability a mouse turns right is 0.55. Suppose their turning pattern follows a binomial distribution.
