The discussion focuses on calculating probabilities from a standard deck of 52 cards. The first problem requires finding the probability of drawing a spade, face card, 3, or club, while the second involves determining the probability of drawing a specific sequence of cards without replacement. Participants express frustration over the lack of guidance and the need for assistance in solving these problems rather than a full lesson. There is a clear request for help with the specific worksheet questions to gain more practice. The conversation highlights the importance of showing work for better understanding and verification of solutions.

We can't conduct a classroom at this site.
Was your teacher absent?
 
I am trying to get help on these specific problems that I am being asked on a worksheet that is all I am not asking to get taught it again since I JUST NEED HELP SOLVING THE QUESTIONS IN ORDER TO OBTAIN MORE PRACTICE WITH THESE TYPE OF PROBLEMS

Thread 'Erroneously finding discrepancy in transpose rule'

Obviously, there is something elementary I am missing here. To form the transpose of a matrix, one exchanges rows and columns, so the transpose of a scalar, considered as (or isomorphic to) a one-entry matrix, should stay the same, including if the scalar is a complex number. On the other hand, in the isomorphism between the complex plane and the real plane, a complex number a+bi corresponds to a matrix in the real plane; taking the transpose we get which then corresponds to a-bi...
