    Smile Probability equation X > number




    Long time lurker, first time poster! All help much appreciated!

    I have one equation being compared to a number:

    X = any positive real number

    X'= (L)+2(Y)+3(Z)

    The value of L, Y, and Z are always between 0-1 and its value can change, but it has a probability associated with it. If I use actual numbers, imagine:

    L=
    0.3-1 (90% of the time),
    0.5-1 (60% of the time),
    0.9-1 (10% of the time)

    Y= 0 or 1 (Y=1, 1% of the time and Y=0, 99% of the time)

    Z=
    0.00-0.25, 25% of the time
    0.25-0.50, 25% of the time
    0.50-0.75, 25% of the time
    0.75-1.00, 25% of the time

    X=2.50

    L, Y, Z are independent variables.

    I am curious as to how I could calculate the probability of X'>X. Is there a model/equation I can use that can calculate such a thing for me?

    Thank you very much everyone!

    Well do you know the distribution for L, Y, and Z for the other values they can take on? Otherwise its going to be really hard to do much of anything.
    I don't have emotions and sometimes that makes me very sad.
