Question 887142
In U.S criminal trials, about 60% of all defendants are found guilty. 
a) if you were to observe 25 criminal trials, what is the expected number of guilty verdicts?
E(x) = np = 25*0.6 = 15
------------------------------------------
 b) how many trials would you need to observe in order to 96% certain of seeing a guilty verdict?
P(0<= x <=?) >= 96
----
? = 19
