It depends how much petrol was put in. If it was a "full tank" draining the tank and the system would be advisable. If it was just a small amount, the mixture can be cut by adding more diesel with some motor oil mixed into it It is a common practice in times of diesel shortages to use motor oil with a small amount of gasoline added to it in place of diesel. You will have to use your own judgment as to how much diesel and/or oil to add.
Have it drained out and change filters
Never put gas in a diesel car. And never put diesel in a gas car. An engine is built to handle one and not the other.

No.
Car will run poorly if at all.
If the engine will run you could drive it, but I would advise against it. The diesel may damage the O2 sensors and catalytic converter. Drain the tank and then fill it up with fresh gasoline. No real damage will be done with the small amount of diesel left.
Siphon out as much as possible and refill with deisel, keep topping up every time you use a gallon or so, I've done this twice and no damage to engine.
Put diesel fuel in a gasoline vehicle and it will not run at all.
