Below is some background information from Lee's Introduction To Smooth Manifolds about slice charts of embedded submanifolds. My question is at the bottom.

What I don't understand in the proof is the part highlighted in red. I don't understand how we can conclude that $S$ is a topological embedding from what we proved so far.

          Up to the point you have highlighted, we have shown that for any point $p$ in $S$, we can define a chart $(psi,V)$, where $V$ is open in $S$ and contains $p$, with $psicolon Vto widehat Vsubset Bbb R^k$ a homeomorphism. The inclusion map $iotacolon Shookrightarrow M$ is a topological embedding because $S$ is given the subspace topology, hence $iota$ is a homeomorphism onto its image.

            Up to the point you have highlighted, we have shown that for any point $p$ in $S$, we can define a chart $(psi,V)$, where $V$ is open in $S$ and contains $p$, with $psicolon Vto widehat Vsubset Bbb R^k$ a homeomorphism. The inclusion map $iotacolon Shookrightarrow M$ is a topological embedding because $S$ is given the subspace topology, hence $iota$ is a homeomorphism onto its image.

                    Probability when a professor distributes a quiz and homework assignment to a class of n students.

                    Image
                    0 0 $begingroup$ Need help with this problem. Suppose our lazy professor collects a quiz and a homework assignment from a class of n students one day, then distributes both the quizzes and the homework assignments back to the class in a random fashion for grading. Each student receives one quiz and one homework assignment to grade. (a) What is the probability that every student receives someone else's quiz to grade, and someone else's homework to grade? (b) What is the probability that no student receives both their own quiz and their own homework assignment to grade? In this case, some students may receive their own quiz, and others may receive their own homework assignment. (c) Compute the limiting probability as n approaches infinity in each case. ...
