If Party A and Party B play a game, the rules are as shown in the flowchart, and the probability of Party A winning is _ _ _ _ _.

Throwing three coins in a row, the following results are obtained:

(positive, positive, positive), (positive, positive, negative), (positive, negative, positive), (positive, negative, negative),

(anti, positive, positive), (anti, positive, negative), (anti, anti, positive), (anti, anti, anti), * * 8 cases,

Among them, "two positive and one negative" appeared three times.

The probability of "two positive and one negative" is 38.

Therefore, the probability of A winning is 1-38=58.

So the answer is 58.
