Answer 2

Answer:

=> To calculate a simple probability, simply take the number of results that fit your requirements and divide by the total possible number of results.

For a standard fair 6 sided die marked 1 thru 6, no results fit your requirement of a 7, and there are 6 possible results. So, we have 0/6, or 0.
