Radar detectors are either powered by their own battery or plug into the cigarette lighter socket. All radar detectors come in three models: no-frills, standard, and fancy. In addition, detectors powered by their own batteries detect either radar or laser, or both, whereas the plug-in types come in models that detect either radar or laser, but not both. How many different radar detectors can you buy? ------------------------------------ choices

Expert Solution
Step 1
The Process of Buying a radar detector can be presented as the following algorithms.
Step1
Choose select the model (no frills, Standard & famly There Hence there are 3 Possible Choices.
Step 2
Choose the way you want the detector to be power
Alternative 1: own Battery
There are 3 choices (detect either radar, or laser or both)
Alternative 2: cigrette lighter socket
There are 2 choices (detect either radar or laser not both)
According to Addition Principle:
There are 3+2=5 choices.
Finally according to multiplication Principle there are 3x5 = 15
