Refer to Exercise 3. Resistors are randomly selected from the box, one by one, until a 100 Ω resistor is selected. a) What is the probability that the first two resistors are both 50 Ω? b) What is the probability that a total of two resistors are selected from the box? c) What is the probability that more than three resistors are selected from the box?
