Question

thirteen 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) = 13, Total number of outcomes (total DVRs) = 100

Step3: Calculate probability

Probability = $\frac{13}{100}=0.13$

Answer:

0.13
