Random.value returns a float between 0 to 1. You can use it to generate percentage random like so:

 if(Random.value > 0.5) //%50 percent chance
 {//code here
 }
 
 if(Random.value > 0.2) //%80 percent chance (1 - 0.2 is 0.8)
 { //code here
 }
 
 if(Random.value > 0.7) //%30 percent chance (1 - 0.7 is 0.3)
 { //code here
 }

You can also say

if(Random.value <= 0.2)

to get a %20 chance without the confusion.
