How do I find the measure of an angle?
Using a Protractor
The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree.

Answer:

5
Explanation:
Remember that odds for plus odds against must be 1. Therefore, 20 out of 50 of the DVRs are defective, so 30 out of 50 would work.
30
50
simplifies into
3
5
, so that would be the probability of you picking out a DVR that works, and the probability of picking one that does not work would be the leftover

5
. Or, if you're answering with a percent, you would have a 60% chance of picking a working DVR.
