[問題] 機率問題
這是交大的考古題
題意看了很多變還是不知道在求甚麼
請各位幫忙一下^^
The probability of head of a random coin is a random variable X
uniform in the interval(0,1)
Find
(a)the probability that at the next tossing of the coin heads will show;
(b)a posterior probability of 0.3<=X<=0.7,given the coin is tossed 10 times
and heads shows 6 times?
我第一題的想法很簡單
只想說表示x的連續均勻函數
不過感覺就點怪
第二小題
我是用條件機率想
P(0.3<=X<=0.7│p=0.6)
P~(o.5,0.6*0.4/10)
去做標準化
不知道這樣對不對
