Blind solution mathematics
A: First of all, there is a prerequisite for the question: that is, Xiao Ming doesn't know the usual scores of the eight players. In this case, the probability of formula 1 and formula 2 is equal. The guess probability of mode 1 is 1/4, and that of mode 2 is 1/4, so the guess probability of mode 1 is the same as that of mode 2.
