    Density Function
    For a density function

    f(x) = 3 (x+4) / 14 for x=0 to x=1
    Find P (2/5 < x < 2/3)

    Please walk me through this problem.
    Thanks

    I'm sorry, is that function P(x) or f(x)?

    Its function f(x)

    It's asking to find the Probability P (2/5 < x < 2/3)

    Sorry then, I'm unfamiliar with the problem :(. I was thinking it could be something else other than probability. I will go research this a bit and hopefully be able to provide and answer. Otherwise you will have to wait for a reply from someone who has a larger knowledge based around statistics

    This is a probability density function. You integrate.
