Choose Random Background During Game

hello everyone .
i want to create a 2D game with infinity background . i have 10 different back ground ad i want that the game choose them randomly and select it as the next image that appears during the game .
what should i do?

hello

1-place an empty gameobject and call it “Background”

2-from the inspector add a sprite renderer

3-create and new script called “RandomBackground” and assign t to the “Background” gameobject

4-write the following code :

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RandomBackground : MonoBehaviour {

    public Sprite[] Backgrounds; //this is an array of type sprite

    public SpriteRenderer Render; //this is a variable of type sprite renderer

	// Use this for initialization
	void Start () {
           Render = GetComponent<SpriteRenderer>(); 
           /*assigning the Render to the object's SpriteRender, this will allow us to access the image from 
           code*/
           Render.sprite = Backgrounds[Random.Range(0, Backgrounds.Length)]; 
           /*this will change the current sprite of the sprite renderer to a random sprite that was chosen 
           randomly from the array of backgrounds */
        }
	// Update is called once per frame
	void Update () {

	}
}

5-on the inspector , type 10 in the Backgrounds input box , it will open 10 slots for you
6-drag and drop the diffrent background images you need from your project panel respectively to the 10 slots you opened .

this should be it , everytime you will start the scene you will get a different background
Please let me know if this helped.
