If MR = 00, the flip-flop does not change state.

If MR = 10, the flip-flop is reset; i.e. Q=0.

If MR= 11, the flip-flop changes state.The input combination

MR = 01 is not allowed.

Give the next state equation for this flip flop"

I have no idea how to solve this, could anyone provide any hints / clarifications that might help me out?
