SUMMARY
The probability of the p-th student being a girl in a line of 10 students depends on the composition of the group. If there are five boys and five girls, the probability is 1/2. Conversely, if the group consists of seven boys and three girls, the probability is 3/10. The formula for calculating the probability of any specific position being occupied by a girl is x/10, where x represents the number of girls in the group.
