A probability question
The hit rate of each shot is 3/7, while the hit rate of each shot is 1/2. If A, two people turn to shoot. The rules of the game began first, and the one is only viented once, and B is twice in each round, and the first investigated. Then the same is the same.
Think about the shooting rate of the A. It is more than one B, and B is doubled, why do you have the same winning probability? First, you will be strong - this is the great advantage that will first start.
