1, I think will increase the probability of the selection.

The reasons are as follows:

If the selection is not replaced, the probability of the player selecting the car is 1/3;

If the selection is changed, the probability of the contestant selecting the car is 1/3*0+2/3*1=2/3.

2, the program source code is as follows:

From random Import *

def once (doors = 3): # Simulation of a single event

Car = randrange (doors) # There's a car parked behind a door

Man = Randrange (doors) # Contestants pre-Select a door

return car = = Man # did the contestants first choose to go to the car
h = 0 # Keep Choosing the number of times you win a car

c = 0 # Change the number of times you choose to win a car

times = Int (1e6) # Number of repetitions of the experiment
For I in Range (times):

If once (): H + = 1

Else:c + = 1

Print ("Maintain selection:", h/times*100, "%\n Change Selection:", c/times*100, "%")

3. The verification result of the operation is as follows:
