The color combinations of the balls in the three boxes are red, white, blue, red, blue, white, red, blue, red, blue, white and red.
(2) Solution: The probability of putting the red ball into each box is the same, and * * * has three boxes.
Therefore, the probability that the red ball can just fit into box 2 is P= 1/3.
Second, the solution: put the lid on the teacup in turn. The first teacup and lid have two combinations, and the second teacup has only one.
Therefore, * * has 2x 1=2 (species).
In both cases, only one collocation is correct and the probability of each collocation is the same.
Therefore, the probability of correct color matching is P= 1/2.
