    Ok, I have this question:

    the probability is in the table below:

    x P(X=x)
    1 0.1
    2 0.2
    3 0.3
    4 0.3
    5 0.1

    b) Given that X1 and x2 are independent observations on X, calculate

    Could someone explain simply how you would do this. thanks

    It's been a while since I've done stats, but wouldn't it just be a case of finding out the probability of getting the same number twice for 1 thru 5 then adding the probabilities up?

    Ie 0.1*0.1 + 0.2*0.2 + 0.3*0.3...
