Compute Probabilities Using the General Multiplication Rule
-Four employees drive to work in the same car. The workers claim they were late to work because of a flat tire. Their managers ask the workers to identify the tire that went flat; front driver's side, front passenger's side, rear driver's side, or rear passenger's side. If the workers didn't really have a flat tire and each randomly selects a tire, what is the probability that all four workers select the same tire?

• A) \(\frac { 1 } { 64 }\)
• B) \(\frac { 1 } { 4 }\)
• C) \(\frac { 1 } { 256 }\)
• D) \(\frac { 1 } { 8 }\)
