The question is:(adsbygoogle = window.adsbygoogle || []).push({});

Rolling a sum of 8 and a sum of 6 BEFORE rolling two sums of 7

Experimental Probability: 55%

Theoretical Probability: 54.5%

How did they do this?

I understand that to get a sum of

8: 13.888%

6: 13.888%

7: 16.666%

6/8: 27.777%

but I dont understand how they figured out those values for theoretical probability...

thanks so much
