Question

eight of the 100 digital video recorders (dvrs) in an inventory are known to be defective. what is the probability that a randomly selected item is defective? the probability is (type an integer or a decimal. do not round )

Explanation:

Step1: Recall probability formula

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

Step2: Identify values

Number of favorable outcomes (defective DVRs) = 8, total number of outcomes (total DVRs) = 100.

Step3: Calculate probability

Probability = $\frac{8}{100}=0.08$

Answer:

0.08
