I have a very simple question about matrix transformations here. I did the question but I just need a verification to see if my work is right. Also, is there a way I could check my answer?

Your answers look good to me.



As for where you can check your answers, there is no software anywhere that could just "check your answer" in general. You can check that the multiplication of the vector by the matrix is correct using any software that can manipulate matrices, but to answer a general mathematical question... well... if you write that software, you will be a rich man.

  • Haha I figured that much out. I guess I was really asking is there an intuitive way to reason out that this is a reasonable answer.

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. ...
