The probability that Xiao Wang kicks Xiao Wang after three kicks (2 *1*1)/(2 * 2 * 2) =1/4.

A * * * kicks three times, each time everyone has two choices, so the denominator is 2*2*2. Starting from Xiao Wang, he can choose between Xiao Li and Xiao Hua, that is, choose one from the other. No matter who Xiao Wang passes it to, this person can only pass it to someone who is not Xiao Wang, and finally he can pass the shuttlecock to Xiao Wang, that is, each person has only one choice for the last two passes.

Xiaohua's probability of kicking Xiao Wang after starting to kick three times is divided into two situations.

Xiaohua is passed to Xiao Wang first: (1* 2 *1)/(2 * 2 * 2) =1/4.

Little Wang Can chooses between Xiao Li and Xiao Hua, and then one of them will pass it on to Xiao Wang.

Xiaohua will be sent to Xiaoli first: (1*1*1) (2 * 2 * 2) =1/8.

Xiaoli can only be passed to Xiaohua, and then from Xiaohua to Xiao Wang.

Both add up to 3/8.

Starting from Xiaoli, the situation is the same as Xiaohua.
