Question 479349
How many green elements are required to make this a legitimate probability distribution if there are a total of 50 elements in this sample? ---
--x---- red----	blue---	orange--brown---green
P(x)---	0.22---	0.08-----0.20----0.30-----?--

---------------------
? = 1 - [0.22 + 0.08 + 0.20 + 0.30]
? = 0.30
===
# of green = 0.3*50 = 15
