This question is about Perfect Codes in Coding Theory: You may use that a perfect code of length 13 and distance 3 exists over GF(3). A soccer betting form contains a list of 13 matches. Next to each listed match there are three fill-in boxes which correspond to the following three possible guesses: “first team wins”, “second team wins” or “tied match”. The bettor checks one box for each match. Describe a strategy for filling out the smallest number of forms so that at least one of the forms contains at least 12 correct guesses. How many forms need to be filled out under this strategy?

3.9. Is the reduced echelon form of a matrix unique? Justify your conclusion. Namely, suppose that by performing some row operations (not necessarily fol- lowing any algorithm) we end up with a reduced echelon matrix. Do we always end up with the same matrix, or can we get different ones? Note that we are only allowed to perform row operations, the "column operations"' are forbidden.
Can someone please explain to me how I can solve this question?
In the Shamir secret sharing scheme, we distribute a secret among q different users as follows. If our secret is a message (m₁,..., mk) from V(k, q) then, we encode it as a codeword of the Reed-Solomon RSk(q) and give one coordinate to each user.

Many online portals now use 2-Factor Authentication. After you login with your username and password, a code is sent to your phone and you have to enter this code. Assume this code is six digits long. What is the likelihood that this code will consist of at least one repeated digit? (zero is a valid digit, meaning an authentication code could consist of all zeroes. Here are examples of authentication codes with repeated digits – 000000, 154443, 112339, 556688). Please show how you would do this in excel, thank you!
