Optimized RNG Chances

[Luke_Sky_Walker]

If you were to arrange an RNG type item system with multiple values and chances like so (This is just a rough example by the way):

function exam(n: text, p: player)
   chance of 5%:
      give {_p} 1 of gold ingot named "%{_n}%"
      stop
   chance of 1%:
      give {_p} 1 of diamond named "%{_n}%"
      stop

command test:
   trigger:
      chance of 1.5%:
         set {_p} to player
         set {_name} to "&bExample"
         examp({_name}, {_p})

Would there by a way to make this kind of code more effective (Ideally to be a lot shorter and with the ability to have a lot more % chances without using up a lot of lines)?

function exam(p: player, c: number, i: item ,t: text):
chance of {_c}%:
give {_p} 1 of {_i} named "%{_t}%"

command /test:
trigger:
exam(player, 5, gold ingot, "&bExample")
