Heads up H, tails up T, then the sample space {hh ht tt} shows that if both coins are heads up, the probability that Xiaoming will do it first is1/4; If both coins are heads up, the probability of Xiaoying doing it first is1/4; If two coins are heads and tails, Xiao Qiang will get 1/2 first. So Xiao Qiang is most likely to do it first. After determining the sample space {H T} of Xiao Qiang's first coin toss, it can be seen that Xiaoming and Xiaoying have the same probability of determining the second and third place.
To sum up, it is unreasonable to determine the order in this way, and the opportunities for individuals to get the first, second and third places are unequal.
