<PRE><B>Question 422542</B>
From an inventory of 48 new cars being shipped to local dealerships, corporate
reports indicate that 12 have defective radios installed. 
What is the probability that out of 8 new cars it just received, a dealership would discover, after testing, that exactly half of the cars have defective radios?
Binomial Problem with n = 8 and p = 12/48 = 1/4
------
P(x = 4) = 8C4(0.25)^4*(0.75)^4 = 0.08652
---------------
