February 5th, Thursday morning's third class, Math class.
Gao Heshuai's booming voice rang out: "Let's look at the last question, a certain university's math department plans to hold two different themed psychological test events on Saturday and Sunday, respectively organized by Teacher Li and Teacher Zhang. It's known that there are n students in the department..."
"(Ⅰ) Find the probability that student A receives notification of the event from Teacher Li or Teacher Zhang;
(Ⅱ) Find the integer m that maximizes P(X=m)."
Gao Heshuai finished reading the question, paused for a moment, and used the method of induction to lay out the process and answer to the first question.
When it was time for the second question, he quickly read out the answer and then tossed the chalk aside.
Relaxedly announcing: "Alright, this exam paper is finished."
The students were left dumbfounded, and Yu Wen raised her hand: "Mr. Gao, you explained every question before, why suddenly not this one?"
