    How Do You Calculate Covariance and Correlation for X ~ U[0,1] and Y ~ U[0,X]?

    Cov(X,Y) = E(XY) - E(X)E(Y)

    Calculating the Probability of a Flush and Straight in Texas Holdem

    If I am dealt an ace and ten of hearts, what is the probability I will get a flush? And what is the probability I get a straight? I want to say the flush is: (11 choose 3)/(50 choose 3) And for the straight: (12 choose 3)/(50 choose 3) I am not sure. Any ideas?

    How Do You Calculate Covariance and Correlation for X ~ U[0,1] and Y ~ U[0,X]?

    I'm stuck on this problem: Let X be uniform[0,1] and Y be uniform[0,X]. Calculate the covariance and correlation between X and Y. thanks
