If the probability of drawing a white ball is half of the probability of drawing a red ball then find the number of white balls in the bag. Solution: Let the number of white balls be n. The number of red balls = 8. Therefore, the possible number of outcomes = n + 8. Now, the probability of drawing a white ball = \(\frac{n}{n + 8}\).
