[問題] 一題統計
For a continuous random variable X, the probability density function f(x)
represents :
(A)the probability at a given value of X
(B)the area under the curve at X
(C)both A and B are correct answer
(D)the height of the function at X
正確答案是(D)
但請問為何不是(B)呢
連續機率密度函數不是指線下面的面積嗎?
怎麼會是(D)的高度呢?
感謝~~
