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.)
Answer
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
