One car must go into any one of the three large-enough spots. The remaining four cars can be distributed among the other four slots 4! = 24 ways. The total number of arrangement possibilities is 3*24 = 72
4*3*2*1*3 there are 4 possibilities for the first space... so u only have 3 options for the fifth spot because 1 car has already parked... now since two cars have parked in the first and last spots you have 3 cars out of the five that can still park.. so 3 can park in the second spot and then 2 can park in the third spot and then 1 in the fourth space.
