Question 511462
A panel containing 4 on/off switches in a row is to be set. Assuming no restrictions on individual switches. Use the fundamental counting principal to find the total number of possible panel setting?? 
-----
1st switch settings: 2 ways
2nd switch settings: 2 ways
3rd switch settings: 2 ways
4th switch settings: 2 ways
----
Total # of possible setts: 2^4 = 16
