<PRE><B>Question 317981</B>
2% of widgets produced are defective. I randomly select two widgets that have been produced by the machine. For the following questions, round to the nearest hundredth.
-------------------------------- 
How many experimental outcomes yield 2 defects?:::(0.02)^2 = 0.0004
---------------------------------------- 
What is the P(no defects)?::: (0.98)^2 = 0.9604
-------------------------------------------------- 
What is the P(one defect)?::: 1-[0.0004+0.9604] = 0.0392
----------------------------------------------------- 
What is the P(two defects)?::: (0.02)^2 = 0.0004  (Do not round for this problem) 
Say we chose three widgets instead of two widgets, how many experimental outcomes would produce exactly one defect?:::
P(one defect) = 3C1(0.02)(0.98)^2 = 3*0.02*0.9604 = 0.0576
