Need some help on my calculation

#1
Basically I used a program to roll 2 dice and see the observed outcomes compared to the expected outcome.
Doing 100 rolls I should expect to see around 17 doubles.

I then added up the values for the critical value and put them in a calculator and got

Does this mean that it's unlikely to get better results than the ones I achieved? or did my test fail and was weighed heavily not by random occurrence?
I'm wondering if I made the calculation wrong in some way.
