Problem 7. A DNA test is such that there is only a individual will match a certain blood sample. Suppose a population of 50,000 inmates is screened using this test. chance that a randomly selected 10,000 a. What is the expected number of matches? b. What is the probability that there will be at least one match? c. What is the probability that there will be at least two matches? d. What does this tell us about screening a population in this way in order to identify the perpetrator of a crime?

A cable will be installed from a farmhouse to a series of telephone poles. Part of the cable will be installed underground, D, with a cost of $260 per foot and part will be installed atop the telephone poles, L, with a cost of $30 per foot. Note: The total cost = the cost of installing along length L + the cost of installing along the length D.
