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 of an event is the number of favorable outcomes divided by the total number of outcomes. Here, favorable outcomes (defective DVRs) = 8, total outcomes (total DVRs) = 100.

Step2: Calculate Probability

Using the formula \( P = \frac{\text{Number of defective DVRs}}{\text{Total number of DVRs}} = \frac{8}{100} \)
Simplify \( \frac{8}{100} = 0.08 \)

Answer:

0.08
