1. 2. 3. 4. 5. In a certain city district, the need for money to buy drugs is given as the reason for 65% of all thefts. What is the probability that exactly 2 of the next 4 theft cases reported in this district resulted from the need for money to buy drugs? A store owner complains that, on the average, 3 bottles per case of a certain brand of softdrink are underfilled. Assuming this is correct, find the probability that a randomly chosen case of this drink will contain at most 4 underfilled bottles. On the average, 7 people per hour use an express teller machine situated inside a commercial complex. What is the probability that, from 3:00-4:00pm on Friday, exactly 7 people will use the teller machine? The probability that a certain production process will produce a defective part is 0.20. Find the probability that a lot of 12 parts will contain exactly 6 defectives. The probability that a patient recovers from a rare blood disease is 0.40. If 15 people are known to have contracted this disease, what is the probability that at least 12 survive?
