you can use random generator class.

   random rand = new random();    string locator = string.format("//div/div[2]/div[{0}]/input", rand.next(5));     // 5 number of elements in list    driver.findelement(by.xpath(locator)).click(); 

this code in c# 1 1 in java. also, change xpath locator if not correct locator of list.
