    Uniform probability distribution

    Okay it says there are 2200 trout in a lake and they are distributed uniformly from 8 - 10 inches and to sketch a uniform probability distribution. I have no idea how, also it says find the probability that i catch one that is between 8.3 to 9.4 inches, if anyone could help with any part of this i'd greatly appreciate it.

    Do you know what a uniform distribution looks like?

    The pdf is equal to 1/2 over [8, 10] and is zero elsewhere.

    The required probability is the area under the pdf over [8.3, 9.4]. I get (1/2)(1.1) = 0.55.

    Then you should make it your business to read something like this

    Uniform Distribution

    or this

    Uniform distribution (continuous - Wikipedia, the free encyclopedia)

    etc. etc.

    Do you have a textbook or class notes?
