Question 912021: Suppose that in a production of spark plugs the fraction
of defective plugs has been constant at over a long
time and that this process is controlled every half hour
by drawing and inspecting two just produced. Find the
probabilities of getting (a) no defectives, (b) 1
defective, (c) 2 defectives. What is the sum of these
probabilities? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! the fraction of defective plugs has been constant at over a long time
and what is that fraction?
