Webb17 dec. 2024 · Total number of balls in the bag = 7+5+n = 12+n. Probability of drawing red ball = 7/12+n. Probability of drawing green ball = 5/12+n. Probability of drawing white ball = n/12+n. Given Probability of not drawing a white ball = 2/3. Thus, the probability of drawing a white ball = 1- 2/3 = 1/3. Therefore, n/12+n =1/3. solving this equation we get ...
