A continuous uniform distribution has a lower bound of zero and f(X)=2. What is P(X≤0.25)?

A) 1.00.

B) 0.25.

C) 0.00.

D) 0.50.

Your answer: A was incorrect. The correct answer was D) 0.50.

The height of a pdf for a continuous distribution is f(X). The area under the pdf must equal one; therefore, the length of the pdf is 0.5. Since the lower bound is zero, the upper bound is 0.5, P(X≤0.25)=0.5.

what does it mean? thanks!

f(X)=2是什么意思？再去看下题目，我的意见是没有这个表达法的
