Resistors. An electrical engineer has two boxes of resistors, with four resistors in each box. The resistors in the first box are labeled 10 ohms, but in fact their resistances are 9, 10, 11, and 12 ohms. The resistors in the second box are labeled 20 ohms, but in fact haveresistances of 18, 19, 20, and 21 ohms. The engineer chooses one resistor from each box and determines the resistance of each. Answer the following:
A. List all possible outcomes in the sample space.
B. List all outcomes in the event B, the event that the second resistor has a resistance less than 19.
C. List all outcomes in the event C, the event that the sum of the resistances is equal to 28.
D. List all outcomes in B∪C.
E. List all outcomes in B(complement) ∩C .
