Question

A panel containing five on off switches in a row is to be set. Assuming no restrictions on individual switches, use the fundamental counting principle to find the total number of possible panel settings

Answer 1

Using the fundamental counting principle we have:

2 x 2 x 2 x 2 x 2 (We have 5 on/off switches , so we have 2 options per switch)

32 ( We multiply to find the total number of possible panel settings​)

The answer would be 32.
