Therefore, corresponding to the case that Team A wins 3: 0, its probability =0.5*0.5*0.5=0. 125, that is, 1/8.

Corresponding to the case that Team B wins 3: 0, the probability is the same, which is also 1/8.

Team a 3: 1 winning probability = 0.5 * 0.5 * 0.5 * 3 = 3/ 16 (because the game won by team b can be in the first, second and third innings, there are three situations).

Team B has the same winning probability of 3: 1, which is also 3: 16.

The winning probability of Team A is 3: 2 = 0.5 * 0.5 * 0.5 * 6 = 3/ 16 (because the two games won by Team B can be in 1-2, 1-3, 1-4, 2-.

Team B has the same winning probability of 3: 2, which is 3/ 16.
