GivenGiven Rusted screw =(1/10) of 600Given Rusted screw =(1/10) of 600=(1/10)×600Given Rusted screw =(1/10) of 600=(1/10)×600=60 secondsGiven Rusted screw =(1/10) of 600=(1/10)×600=60 secondsProbability of rusted screw=60/600=1/10Given Rusted screw =(1/10) of 600=(1/10)×600=60 secondsProbability of rusted screw=60/600=1/10Probability ( of not rusted screw)=1− Probability ( of rusted screw)Given Rusted screw =(1/10) of 600=(1/10)×600=60 secondsProbability of rusted screw=60/600=1/10Probability ( of not rusted screw)=1− Probability ( of rusted screw)=1−1/10Given Rusted screw =(1/10) of 600=(1/10)×600=60 secondsProbability of rusted screw=60/600=1/10Probability ( of not rusted screw)=1− Probability ( of rusted screw)=1−1/10=(10−1)/10Given Rusted screw =(1/10) of 600=(1/10)×600=60 secondsProbability of rusted screw=60/600=1/10Probability ( of not rusted screw)=1− Probability ( of rusted screw)=1−1/10=(10−1)/10=9/10IHOPETHISHELPSTotal screws in the box = 600

One tenth of 600 = 60

P(getting a good screw) = One tenth of 600 / Total screws in the box = 60/600 = 1/10

The probability of getting a good screw is
