A) 0.5
B) 0.05
C) 0.2
D) 20
Correct Answer: B
Solution :
Since there are 200 plates, \[n(S)=200\]. Let B be the event of picking a defective plate. Then, \[n(B)=10\]. The probability of picking a defective plate \[=P(B)=\frac{n(B)}{n(S)}=\frac{10}{200}=0.05\]You need to login to perform this action.
