Question

nine of the 50 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: Identify favorable and total outcomes

Favorable outcomes (defective DVRs) = 9, total outcomes (total DVRs) = 50.

Step2: Apply probability formula

Probability = $\frac{\text{Favorable outcomes}}{\text{Total outcomes}}=\frac{9}{50}= 0.18$

Answer:

0.18
