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.
IlI. The probability that a patient recovers from a rare blood disease is 0.3. If 20 people are known to have contracted this disease, (a) exactly 3 survive; (b) at least 2 survive, (c) the mean and variance of this process. (20 points)
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...
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?
Exercise4 It is known that the serum cholesterol levels of 18-year-old subjects population follow a Normal distribution with mean 196mg/dLi and a standard deviation 31 mg/dLi. For a subject selected at random, what is the probability that 1. The serum cholesterol level will be 220 or more? 2. The serum cholesterol level will be 230 or less? 3. The serum cholesterol level wil be between 130 and 160 (both included)? 4. At what value of serum cholesterol level will 70%...

3) A human gene carries a certain disease from the mother to the child with a probability rate of 30%. That is, there is a 30% chance that the child becomes infected with the disease. Suppose a female carrier of the gene has five children. Assume that the infections of the five children are independent of one another. Find the probability that at least one of the children get the disease from their mother.
It’s known that 2 % of people in a certain population have the disease. A blood test gives a positive result (indicating the presence of disease) for 95% of people who have the disease, and it is also positive for 3% of healthy people. One person is tested and the test gives positive result. a. If the test result is positive for the person, then the probability that this person actually has a disease is _________ b. If the test...
