Hello, I am hoping someone can help me with this problem.

An urn contains 10 balls: 4 red and 6 white.  A second urn contains 16 red
balls and an unknown number of white balls.  A single ball is drawn from each urn.  The
probability that both balls are same color is .44.  Calculate the number of white balls
in the second urn.

I have tried this to solve for the total number of balls in the second urn 4/10*16/x=.44, but get a value for x that is way too small. I have a feeling I am missing something. Any ideas anyone? Please HELP! big_smile
