Question:

The breakdown voltage of a randomly chosen diode of a certain type is normally distributed with mean 42V and variance 2.56V.

a. Calculate the probability that the voltage of a diode is between 40V and 43V.

b. Calculate the value of the voltage such that only 20% of all diodes with voltages exceeding that value.

c. If five diodes are independently selected, calculate the probability that the at least one diode has a voltage exceeding 43V.
