Get chance to use an item with a listed percentage

Currently, I have a list created in a config that has an item id and a percent chance that the item listed will be used.

Code:

list:
  - 1|75
  - 2|25

The 1 in the "1|75" entry is the item id, and the 75 is the percent chance that that entry will be used.

I am currently having trouble on doing this, as I do not know how to correctly calculate the percent.

Code:

for(int x = 0; x < getConfig().getList("list").size(); x++){
    String entry = (String) pc.getConfig().getList("list").get(x);
    String[] split = entry.split("|");
    int itemID = Integer.parseInt(split[0]);
    int chance = Integer.parseInt(split[1]);

The above is the code I am currently using to get an entry its item id and chance. How would I use the percent chance listed to correctly determine which entry to use in the list?

 

Code:java

 
Random rnd = new Random();
if(rnd.nextInt(100) + 1 <= chance)
{
    //do stuff
}
