Hi I have a problem and I ma afraid that my math skills has deserted me.

As per the attached exell sheet I want to try and forecast percentage wise what the next no in Cell A84 might be.

In C1 - 4 is the amount of times a no appeared in the worksheet
D1 -4 is the percentage times a certain no appeared on the sheet
E3 is the percentage times 1 ,2 and 3 appeared on the sheet.

What I want to try and forecast is 1. what is the chances % of a 1 to appear in A84
2. what is the chances % on either a 1 , 2, or 3 to appear in A84
3. what is the chance % of a 0 to appear on A84
