The resistance for resistors of a certain type is a random variable X following a normal distribution with a mean of 9 ohms and a standard deviation of 0.4 ohms. A resistor is acceptable if its resistance is between 8.6 and 9.8 ohms. a. What is the probability that a randomly chosen resistor is acceptable? b. What is the probability that out of four randomly and independently selected resistors, two are acceptable?
