\[\sum_{i=1}^{k}(O _{i}E _{i})^{2}/(E _{i})\] Where K is the number of categories. O sub i is the observed outcomes of i and E sub i is the expected number of outcomes. Do you have a software available to you such as StatCrunch?

That equation is your test statistic. It will give you your value to put into the table to determine your PValue.

Since I don't know the exact commands for Excel, I'll explain that by hand. You take your observed value for each number/category (i), and subtract the expected value, which is calculated by your number of samples times the probability of i. (Observed value of 1  expected value of 1)^2/(expected value of 1) + (Observed value of 2  expected value of 2)^2/(expected value of 2) + etc.
