It is known that the prevalence of Leptospira in the cattle population is 30%. Each animal in the population is either seropositive for Leptospira or not. Blood samples from eight cattle are randomly selected from the population. What is the probability that exactly two of the cattle are positive for Leptospira? [Hint: this is a Binomial problem.]

    One percent of all individuals in a certain population are carriers of a particular disease. A diagnostic test for this disease has a 95% detection rate for carriers and a 4% detection rate for non-carriers. Suppose the test for this is applied independently to two different blood samples from the same randomly selected individual. Hint: Use Notation A= {no disease} A'={disease} B1= {1st test positive} B2={2nd test positive} a) What is the probability that the first test is positive? b)...
