Question

ten 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) = 10, total outcomes (total DVRs) = 100.

Step2: Calculate Probability

Using the formula \( P = \frac{\text{Number of defective DVRs}}{\text{Total number of DVRs}} = \frac{10}{100} = 0.1 \)

Answer:

0.1
