1) You purchase 12 resistors and test them to see if they meetthe requirement you need for Resistance. You need the resistance tobe close to the 1000 ohms that they are labeled as. The probabilitythe resistor matches your requirement is 0.2.
a) What is the probability that 2 resistors are good?
b) What is the probability that 2 or more of the resistors aregood?
c) What is the expected number of resistors that are good?
