Question 527849: A pet supplier has a stock of parakeets of which 10% are blue parakeets. A pet store orders 3 parakeets from this supplier. If the supplier selects the parakeets at random, what is the chance that the pet store gets exactly one blue parakeet? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A pet supplier has a stock of parakeets of which 10% are blue parakeets. A pet store orders 3 parakeets from this supplier. If the supplier selects the parakeets at random, what is the chance that the pet store gets exactly one blue parakeet?
--------------
Binomial Problem with n = 3 and p(blue parakeet) = 0.1
---------
P(x = 1) = 3C1*0.1^1*0.9^2 = 0.2430
