Q1. A small voting district has 101 female voters and 95 male voters. A random sample of 10 voters is drawn. 1. What is the probability exactly 7 of the voters will be female? 2. What is the probability that at most 7 of the voters will be female? 3. What is is the probability that at least 7 of the voters will be female? Q2 Each of 12 refrigerators of a certain type has been returned to a distributor because of an audible, high-pitched, oscillating noise when the refrigerator is running. Suppose that 7 of these refrigerators have a defective compressor and the other 5 have less serious problems. The technition looks at 6 refrigerators, what is the probability that exactly 5 have a defective compressor?
