(a) How many ways are there to draw 3 resistors from a box of 500 resistors?
(b) How many ways are there to draw 3 resistors from a group of 495 100 k resistors?
(c) Calculate the probability of drawing 3 100 k resistors from a box of 500 resistors, where 495 are 100 k resistors and 5 are 10 k . Use your results from part (a) and (b) to find this probability.
(e) How many ways are there to draw 3 resistors from a group of 5 10 k resistors?
(f) Calculate the probability of drawing 3 10 k resistors from a box of 500 resistors, where 495 are 100 k resistors and 5 are 10 k . Use your results from part (a) and (e) to find this probability.
