Expected Number of Distinct Balls Drawn with Replacement

Problem Statement:A box contains 5 balls labeled from 1 to 5. If three balls are drawn with replacement, let X be the number of distinct balls that are drawn at least once in the three draws. Find E(X). Answer: \(P(X=3)=\frac{5}{5}\times\frac{4}{5}\times\frac{3}{5}=\frac{12}{25}\) \(P(X=2)=\frac{5}{5}\times\frac{1}{5}\times\frac{4}{5}\times\text{C}^3_2=\frac{12}{25}\) \(P(X=1)=\frac{5}{5}\times\frac{1}{5}\times\frac{1}{5}=\frac{1}{25}\) \(E(X)=3 \times P(X=3)+2 \times P(X=2)+1 \times P(X=1)\) \(=3\times\frac{12}{25}+2\times\frac{12}{25}+1\times\frac{1}{25}\) \(=\frac{61}{25}\) There are approximately 2.44... » read more

謙遜:給中學生的一堂品德課

謙遜是每個人都應該培養的美德,對於正在成長、認識自我與世界的中學生而言尤其重要。它意味著保持謙卑、不炫耀,並尊重他人。謙遜能幫助我們建立良好的人際關係、保持腳踏實地的態度,並贏得他人的尊敬。 為什麼謙遜很重要? 首先,謙遜使人保持謙卑。當我們取得成就(例如贏得比賽或考出好成績)時,感到自豪是正常的,但不應該過度吹噓。謙遜的態度意味著我們能肯定自己的成功,同時不讓他人感到難堪。人們更欣賞那些自信卻不驕傲的人。 其次,謙遜能鞏固友誼。沒有人喜歡總是自誇的人。相反地,謙遜的人懂得傾聽、欣賞他人的優點,並平等對待每個人,這樣才會讓身邊的人感到自在。 第三,謙遜教會我們尊重自己與他人。當我們在衣著、言行上保持得體時,展現的是對內在品質(如善良與智慧)的重視,而非外在的炫耀。這能幫助我們專注於真正重要的事——成為更好的人。 如何實踐謙遜? 結語 謙遜是一項重要的品德,能幫助我們成為受人尊敬、善良的人。中學生若能保持謙卑、欣賞他人,並重視內在價值,便能建立真摯的友誼,贏得他人的尊重。請記住,真正的優秀不在於炫耀自己,而在於自信而不自滿。讓我們從言行中實踐謙遜的美德吧!
