Answer:

The probability of the first draw is 100%, because the bead will be either red or white. For the second draw, a different color must be drawn.

So, if draw 1 is white, then the probability of draw 2 being red is 7/10. and if the first draw is red, then the probability of draw two being white is 5/10.
