Suppose that the fraction of foo() that is parallelizable is $\alpha$. Then the total execution time with $n$ cores is: the non-parallelizable execution, done by only one core: $(1- \alpha)\times 20$ the parallelizable execution: $\alpha \times 20 \times \frac{1}{n}$ Then, for the first question, we have to consider that the number of cores is $3$, and the ...
