Exercise - An electrical engineer has on hand two boxes of resistors, with four resistors in each box. The resistors in the first box have 9, 10, 11, and 12 ohms. The resistors in the second box have 18, 19, 20, and 21 ohms. Let's take a resistor from each box, a) List the outcomes in S. b) Let A denote the event that the first resistor has a resistance greater than 10. What outcomes are in A? c) Let B be the event that the second resistor has a resistance less than 19. What outcomes are in B?
