各位大大好 小弟上課遇到了一提問題 思考很久實在無頭緒 想請大家幫幫忙 這關西到我能不能畢業 題目為以下 如能成功 小弟湧泉以報 (Option 2) An urn has m + n balls, m of which are black and n of which are white. Suppose we draw one ball at a time from the urn without replacement and take note of the color of each ball drawn in a sequence. Let U be the runs statistic in the sense of [1] in a sequence of m + n = 8 responses, e.g., one possible outcome would be BBWBBWWB and U = 5 when m = 5 and n = 3. (a) Compute the distribution of U when m = 6 and n = 4. 如在上面講不好說的話 以下是我的mail [email protected] 必當面感恩 --
