1 3 0 2 ← remainder
Here we're discussing the "nth partial sum of a geom series."
1 - r^n
The formula for that is s(n) = a(1) ---------------
1-r
We can subst. the given values and see where that takes us:
1 - (-2)^6 1 - 64
105 = a(1)*---------------- = ----------*a(1) = -21*a(1)
1-(-2) 3
105
Solving this for a(1): a(1) = --------- = -5 (answer)
-21
Total books = 6 + 5 + 4 + 3 = 18
Adventure books = 3
P(Adventure books) = 3/18 = 1/6
Answer: 1/6
