The probability that a brand A widget is defective is x, the probability that a brand B widget is defective is 0.06, and the probability that a brand C widget is defective is 0.04. There are 40 brand A widgets, 35 brand B widgets, 25 brand C widgets, and nothing else in a container. If a widget is selected at random from the container, the probability that the widget selected is defective is 0.053. What is the value of x?	Answers:
A) 0.05	B) 0.055	C) 0.07	D) 0.1	E) 0.2
Given probability of defective items in each brand,   So, the number of items defective in brand A=x*40, in brand 0.055=0.06*35 and brand C=0.04*25   Total number of widgets=40+35+25= 
<gadget id="calculator">40+35+25</gadget>
<output>100</output>
100   the probability that the widget selected is defective is 0.053=(x*40+0.06*35+0.04*25)/100   =&gt; 40x+2.1+1=5.3   =&gt;40x = 2.2   &gt;x=2.2/40= 
<gadget id="calculator">2.2/40</gadget>
<output>0.055</output>
0.055   Ans 0.055
<result>B</result>
