A combination lock like the one shown has three dials. Each of the dials has numbers ranging from 0 to 4. How many different combinations are possible with the lock? Please show all work
I don't see any combination lock!!. But, if repeats are allowed, then each dial has: 4^4 combinations. Since you have 3 dials, then: (4^4)^3=4^12=16,777,216 combinations possible
