Each stone was 2.57 meters long.
You do 7.71/3 to get your answer.
Let n be the number of expected free throw until she makes the first throw.
Suppose the number of throws are 10, Then she will make 8 of the 10 throws. On 5 throws, she make 4 (80% of 5) and on 2 throws, she makes 1.6, it means one throw. We deduce that the expected number of free throws until she makes one is 2.

A9=A1+(n-1)
-2.75+(8*0.25)
-2.75+2=-0.75
