<PRE><B>Question 116620</B>
A quality control inspector found flaws in 13 out of 150 sweaters. 

Here is the question: Find the probability that a sweater has a flaw.
P(flaw) = 13/150
-----------------------

 How many will not have flaws.
150-13 = 137 will not have flaws
====================
