Why not apply the approach from math.stackexchange.com/questions/745646/…, I intentionally did not answer the second question, it is exactly the same, no?

@ScottGoddard but the problem says that "$30\%$ of the professors who received this material adopted the book", so $(S,A) = 0.3 \times 0.8 = 0.24$!

comment Limits: $\lim_{x\to0^+}xe^\frac{-1}x$ and $\lim_{x\to0^-}xe^\frac{-1}x$
Can you please exhibit at least some attempt at solving the problem yourself? Then we can comment and give some hints. This is not the "society of people who do your homework for you."
