An opaque bag contains 50 balls in only two colors, red and white. Remove 2 balls from the bag one by one without replacement. What is the total number of white balls in the bag?
(1)The probability of taking out the white ball for the first time is $$\frac{1}{5}$$.
(2)The probability that the ball taken out are both red is $$\frac{156}{245}$$.
