[問題] Hogg書上的兩個問題@@
1. p.19 1.2-18
let the interval[-r,r]be the base of a semicircle.
if a point is selected at random from this interval,
assign a probability to the event that the length of the
perpendicular segment from the point to the semicircle is
less than r/2.
2.P.38 1.4-18
bowl A contains three red and two white chips.
and bowl B contains four red and three white chips.
A chip is drawn at random from bowl A and transferred to bowl B.
Compute the probability of then drawing a red chip from bowl B?
第一題我看不太懂他要問什麼 而且後面沒有偶數題的答案 不知從何解起..
第二題我看得懂題目 可是我不知道怎麼解 有高手能幫幫忙嗎 囧
抱歉 因為hogg書上沒有答案 能否順便提供答案 如果有詳解更好^^
