How do i access the variables of a class that is in an array?

I have a class called Data with 2 variables, Sprite and int. This class is placed inside of an array. How do i access the variables of the class for each element in the array? I looked for hours but i don't think i have found my answer, or its possible i did and didn't realize it because i'm pretty new to C# and Unity, so any help is appreciated.

Just a little insight as to what i'm trying to do, its a 3x3 slot machine and i want to have it choose a sprite but each sprite has a percent chance to be picked. I have not setup any code for checking percentages or anything because i have been stuck here for a few hours trying to figure this out lol. There is a large chance i am doing this totally wrong so sorry if it is.

 public class IntUtil : MonoBehaviour {
 
 
     public class Data
     {
         public Sprite sprite;
         public int chance;
     }
 
 // slots array is just the image that will show the random sprite that is chosen.
     public Image[] slots;
     public Data[] dataArray;
     public Button spinButton;
        
     private float timer = 0f;
     
 
 
     private void Start()
     {
         ChangeImage();
     }
 
     private void Update()
     {
         timer -= Time.deltaTime;
 
         if (timer > 0f)
         {
             spinButton.enabled = false;
              
             ChangeImage();
         }else
         {
             spinButton.enabled = true;
             
         }
 
              
         
     }
 
 
 
 
 
     private void ChangeImage()
     {
 
         foreach (Image randImage in slots)
         {
            // here is where i am trying to access the sprite variable that is inside the class that is part of the data array. 
             int num = Random.Range(0, dataArray.Length);
         randImage.sprite = dataArray.sprite[num];
 
             
         }
 
 
     }
 
     public void StartTimer()
     {
 
         timer = 1.5f;
 
     }
 
 
     void CheckPercentage()
     {
         
     }
 }
