The coefficients of friction between a block of mass 0.5 kg and a surface are μs = 0.75 and μk = 0.45. Assume the only other force acting on the block is that due to gravity. What is the magnitude of the frictional force (in newtons) on the block if the block is at rest and the surface is horizontal? Use g = 9.79 m/s2

The maximum frictional force will be. 75 (mg), but since no other forces are acting on the block, the actual frictional force has 0 magnitude. Seems like kinda a trick question.
