How can I make a script choose from possabilities and do something with it? [Solved]
To put it simply I have eggs which will hatch into dinosaurs kind of at random but with probabilities. I believe I have the probabilities part is correct but I'm not sure how to make the script do something with the probabilities. What I mean is I dont know how to make the script chose one of the probabilities and make that dino "hatch" from it. This is very important for our game and I couldn't find help anywhere else any help is greatly appreciated. Im sorry for the question but I'm not very experienced scripting.
The script of probabilities
local Dilo = game.Workspace.Dilophosaurus
local Pachy = game.Workspace.Pachy
local Trike = game.Workspace.Triceratops
local Coeluro = game.Workspace.Coelurosaur
local Compy = game.Workspace.Compy
local chances = {
['Dilo'] = 20,
['Pachy'] = 20,
['Trike'] = 10,
['Coeluro'] = 20,
['Compy'] = 30,
}
local results = {}
table.foreach(chances, function(key, value)
for i = 1, value do
table.insert(results, key)
end
end)
local random = math.random(#results)

the simplest way to do this is through fractions. I have tried so hard to find ways but this is the best one here is an example:
local random=math.random(0,100)
local randomchoice
if random=<50 then
randomchoice="apple"
else
randomchoice="orange"
end
if you want to go further into making the dinos appear just ask cause i know a good amount about scripting!
here's the another example: i personally like to go to 1000 or even 10,000 for for fractions, because this helps you make rare items
--Dilo = 20%
--Pachy = 20%
--Trike = 10%
--Coeluro = 20%
--Compy = 30%
local random=math.random(0,100)
local randomchoice
if random=<20 then
randomchoice="Dilo"
elseif random=<40 and random not =<20 then
randomchoice="Pachy"
elseif random=<50 and random not =<40 then
randomchoice="Trike"
elseif random=<70 and random not =<50 then
randomchoice="Coeluro"
elseif random=<100 and random not =<70 then
randomchoice="Compy"
end

So now I changed the script to this, switching =< to <= and instead of and random not I just did and random >=. Example: It chooses a "Pachy" at 25% or less than 40 but greater than 15 which is 25 difference. Credit to zendaya774 for the help.
local random=math.random(0,100)
local randomchoice
if random <= 15 then
randomchoice = "Dilo" --15%
print ("Dilophosaurus Hatched!")
elseif random <= 40 and random >= 15 then --25%
randomchoice = "Pachy"
print ("Pachy Hatched!")
elseif random <= 55 and random >= 40 then --15%
randomchoice = "Trike"
print ("Triceratops Hatched!")
elseif random <= 70 and random >= 55 then --15%
randomchoice = "Coeluro"
print ("Coelurosaur Hatched!")
elseif random <= 100 and random >= 70 then --30%
randomchoice = "Compy"
print ("Compy Hatched!")
end
