nine of the 200 digital video recorders (dvrs) in an inventory are known to be defective. what is the probability you randomly select a dvr that is not defective? the probability is □. (type an integer or a decimal. do not round.)

nine of the 200 digital video recorders (dvrs) in an inventory are known to be defective. what is the probability you randomly select a dvr that is not defective? the probability is □. (type an integer or a decimal. do not round.)

Answer

Explanation:

Step1: Calculate the number of non - defective DVRs

The total number of DVRs is 200 and the number of defective DVRs is 9. So the number of non - defective DVRs is $200 - 9=191$.

Step2: Calculate the probability

The probability $P$ of selecting a non - defective DVR is the number of non - defective DVRs divided by the total number of DVRs. So $P=\frac{191}{200}=0.955$.

Answer:

$0.955$
