推 goshfju:F(x)=P(X≦x) 慢慢積就好啦 09/29 00:33
→ goshfju:∫1/(b-2)dx from 0 to x = x/(b-2) 09/29 00:34
→ goshfju:∫1/(b-2)dx from 0 to a = a/(b-2) 09/29 00:35
→ goshfju:∫1/(b-2)dx from 0 to a + ∫1/(b-2)dx from a+2 to x 09/29 00:36
→ goshfju:= (x-2)/(b-2) 我沒仔細算 純粹抄你給的解答 09/29 00:36
→ StrKO:感謝解答^_^ 09/29 10:58
推 c3k01:這題建議你把圖畫出來 一切會豁然開朗 09/29 12:13
