Question 1180239: The probability that I find defective bulb in a supermarket display is 0.16. Suppose I inspect 15 bulbs, Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Need more information. If the question is what is the probability I will find 2 defective bulbs,
P(2)=15C2*0.16^2*0.84^13
=0.2787
can do with binomialpdf(15,0.16,2)=0.2787
This is one example of what could be asked.
