The density curve must satisfy two important conditions.
These two conditions are: 1- The total area under the density curve MUST BE equal to 1. (Area total = 1) 2- Every point that is on the curve must have a vertical height that is equal to or greater than zero (vertical height for each point ≥ zero)<span> </span>
It depends on how many colors of gumballs there are and how many gumballs there are in total. With those, we can set the fraction to each gumball color.
