[機統] Exponential Distribution's CDF
根據機率課本已知
Pr[X < t] = 1 - exp(-λt)
現在如果改成已知 X1 X2 分別為獨立產生的exponential random number (同λ)
請問 Pr[X1+X2 < t] 的機率該怎麼求呢
一開始想說用 Pr[X1<t]*Pr[X2<t] 後來仔細一想又覺得怪怪的
不好意思麻煩大家了

《Sometimes Love Just Ain't Enough》 Yan-zi
"But there's a danger in loving somebody too much.
And its sad when you know it's your heart you can't trust.
There's a reason why people don't stay where they are.
Baby sometimes love just ain't enough."
