Therefore, the game of touching the ball can be designed as follows: there are 24 balls in a bag, all of which are the same except the color, including 4 red balls, 8 white balls and 12 yellow balls. Touch any ball from it, and calculate the probability of touching red, white and yellow balls respectively.
(2) According to the meaning of the question, the number of red balls =38×24=9, and the number of yellow balls = 16×24=4.
Therefore, the game of touching balls can be designed as follows: there are 24 balls of the same color in a bag, including 9 red balls, 1 1 white balls and 4 yellow balls. Touch any ball from the inside, and calculate the probability of touching the red and yellow balls respectively.
