1. The probability of a sniper hitting a target is %. If he shoots 20 times, what is the probability that he hits the target at exactly 8 times. 2. It has been determined that 30% of drivers do not wear seatbelts and 10% show traces of alcohol when checked at checkpoints. Also, the two violations are independent of each other. If an officer stops 20 drivers at random, calculate the probability that exactly 2 of the drivers have committed any of the two offenses.
