@yellowboy06 You just need to copy it's line. If you want to increase the probabilty based on vehicle model, then this one;
<VehicleModels> <Vehicle>police</Vehicle> <Vehicle>police</Vehicle> <Vehicle>police2</Vehicle> </VehicleModels>This means 66% chance police will spawn, 33% chance police2 will spawn. So you can add 2 or 3 lines of police, police2 and police3 and 1 line of police4. This also applies to the peds as well.
<PedModels> <Ped>S_M_Y_Sheriff_01</Ped> <Ped>S_F_Y_Sheriff_01</Ped> <Ped>S_F_Y_Sheriff_01</Ped> </PedModels>This will spawn 66% chance of female, 33% chance of male sheriff.
If you want to edit this as a dispatch group (for example you can make police1, 2 and 3 as POLICE, police4 is DETECTIVE), (same with pranger too) then you can do this one;
<DispatchVehicleSets> <Dispatch>POLICE</Dispatch> <Dispatch>POLICE</Dispatch> <Dispatch>DETECTIVE</Dispatch> </DispatchVehicleSets>Feel free to increase the probability even more if you still see it too often.
