推 goshfju :U~U(0,1) , X|U=p~Bin(n,p) 求f(x) 05/05 09:42
→ goshfju :f(x,p)=f(p)f(x|p) , f(x)=∫f(x,p)dp 05/05 09:43

題目如下:
Let U be a uniform random variable on interval(0,1). Suppose that the
conditional distribution of X, given U = p, is binomial with parameter(n,p).
Find the probability mass function of X.
感謝回答! :]
